First, we use it to study attractive, spherically symmetric impurity-boson interactions for which the linear rotor can be mapped onto a static impurity.

This approximation assumes that the timescale of the laser-molecule interaction is significantly shorter than the internal rotational period of the molecule, resulting in the rotational motion being instantaneously “frozen” during the interaction. This simplified description of the laser-molecule interaction is incorporated in various theoretical models predicting rotational dynamics of molecules driven by short laser pulses. In this theoretical work, we develop an effective theory for ultrashort laser pulses by examining the full time-evolution operator and solving the time-dependent Schrödinger equation at the operator level. Our findings reveal a critical angular momentum, lcrit, at which the impulsive limit breaks down. In other words, the validity of the sudden approximation depends not only on the pulse duration but also on its intensity, since the latter determines how many angular momentum states are populated. We explore both ultrashort multicycle (Gaussian) pulses and the somewhat less studied half-cycle pulses, which produce distinct effective potentials. We discuss the limitations of the impulsive limit and propose a method that rescales the effective matrix elements, enabling an improved and more accurate description of laser-molecule interactions."}],"oa_version":"Preprint","scopus_import":"1","main_file_link":[{"open_access":"1","url":"https://doi.org/10.48550/arXiv.2307.07256"}],"month":"02","intvolume":" 109","citation":{"short":"V.

They are, however, often optimized to address a specific type of problem. Here, we present the design and implementation of a 6Li-based quantum gas platform that provides wide-ranging capabilities and is able to address a variety of quantum many-body problems. Our two-chamber architecture relies on a robust combination of gray molasses and optical transport from a laser-cooling chamber to a glass cell with excellent optical access. There, we first create unitary Fermi superfluids in a three-dimensional axially symmetric harmonic trap and characterize them using in situ thermometry, reaching temperatures below 20 nK. This allows us to enter the deep superfluid regime with samples of extreme diluteness, where the interparticle spacing is sufficiently large for direct single-atom imaging. Second, we generate optical lattice potentials with triangular and honeycomb geometry in which we study diffraction of molecular Bose-Einstein condensates, and show how going beyond the Kapitza-Dirac regime allows us to unambiguously distinguish between the two geometries. With the ability to probe quantum many-body physics in both discrete and continuous space, and its suitability for bulk and single-atom imaging, our setup represents an important step towards achieving a wide-scope quantum simulator.","lang":"eng"}],"oa_version":"Published Version","file_date_updated":"2024-03-04T07:53:08Z","department":[{"_id":"MiLe"}],"date_updated":"2024-03-04T07:55:29Z","ddc":["530"],"article_type":"original","type":"journal_article","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)"},"status":"public","keyword":["General Physics and Astronomy"],"_id":"15053"},{"date_updated":"2024-03-25T07:36:55Z","department":[{"_id":"MiLe"}],"_id":"15167","article_type":"original","type":"journal_article","status":"public","publication_identifier":{"issn":["2469-9926"],"eissn":["2469-9934"]},"publication_status":"published","language":[{"iso":"eng"}],"issue":"3","volume":109,"abstract":[{"text":"We perform a diagrammatic analysis of the energy of a mobile impurity immersed in a strongly interacting two-component Fermi gas to second order in the impurity-bath interaction.

Here, we discuss a Caldeira-Leggett-type model that can be used to propose and interpret quantum simulators of this problem in cold Bose gases. First, we derive a master equation that describes the model and explore it in a one-dimensional (1D) setting. To validate the standard assumptions needed for our derivation, we analyze available experimental data without SOC; as a byproduct, this analysis suggests that the quench dynamics of the impurity is beyond the 1D Bose-polaron approach at temperatures currently accessible in a cold-atom laboratory—motion of the impurity is mainly driven by dissipation. For systems with SOC, we demonstrate that 1D spin-orbit coupling can be gauged out even in the presence of dissipation—the information about SOC is incorporated in the initial conditions. Observables sensitive to this information (such as spin densities) can be used to study formation of steady spin polarization domains during quench dynamics.","lang":"eng"}],"oa_version":"Published Version","scopus_import":"1","month":"01","intvolume":" 5","publication_identifier":{"issn":["2643-1564"]},"publication_status":"published","file":[{"access_level":"open_access","relation":"main_file","content_type":"application/pdf","checksum":"6068b62874c0099628a108bb9c5c6bd2","file_id":"12546","success":1,"creator":"dernst","date_updated":"2023-02-13T10:38:10Z","file_size":865150,"date_created":"2023-02-13T10:38:10Z","file_name":"2023_PhysicalReviewResearch_Ghazaryan.pdf"}],"language":[{"iso":"eng"}],"volume":5,"issue":"1","ec_funded":1},{"file":[{"content_type":"application/pdf","relation":"main_file","access_level":"open_access","success":1,"checksum":"c0c040063f06a51b9c463adc504f1a23","file_id":"13253","file_size":2121252,"date_updated":"2023-07-19T06:55:39Z","creator":"dernst","file_name":"2023_JourPhysChemistry_Wei.pdf","date_created":"2023-07-19T06:55:39Z"}],"language":[{"iso":"eng"}],"publication_identifier":{"eissn":["1948-7185"]},"publication_status":"published","volume":14,"issue":"27","ec_funded":1,"oa_version":"Published Version","abstract":[{"lang":"eng","text":"A rotating organic cation and a dynamically disordered soft inorganic cage are the hallmark features of organic-inorganic lead-halide perovskites.

In this work, we use the fact that the polarizability of the organic cation strongly depends on the ambient electrostatic environment to put the molecule forward as a sensitive probe of the local crystal fields inside the lattice cell. We measure the average polarizability of the C/N–H bond stretching mode by means of infrared spectroscopy, which allows us to deduce the character of the motion of the cation molecule, find the magnitude of the local crystal field, and place an estimate on the strength of the hydrogen bond between the hydrogen and halide atoms.

To explain their origin, it is necessary to study how electromagnetic fields interact with these systems. We address this problem here by studying two classical quantities: Faraday rotation and the complex refractive index in a paradigmatic perovskite CH3NH3PbBr3 in a broad wavelength range. We find that the minimal coupling of electromagnetic fields to the k⋅p Hamiltonian is insufficient to describe the observed data even on the qualitative level. To amend this, we demonstrate that there exists a relevant atomic-level coupling between electromagnetic fields and the spin degree of freedom. This spin-electric coupling allows for quantitative description of a number of previous as well as present experimental data. In particular, we use it here to show that the Faraday effect in lead halide perovskites is dominated by the Zeeman splitting of the energy levels and has a substantial beyond-Becquerel contribution. Finally, we present general symmetry-based phenomenological arguments that in the low-energy limit our effective model includes all basis coupling terms to the electromagnetic field in the linear order."}],"volume":130,"issue":"10","language":[{"iso":"eng"}],"publication_status":"published","publication_identifier":{"issn":["0031-9007"],"eissn":["1079-7114"]},"article_number":"106901","title":"Spin-electric coupling in lead halide perovskites","article_processing_charge":"No","external_id":{"isi":["000982435900002"],"arxiv":["2203.09443"]},"author":[{"first_name":"Artem","id":"37D278BC-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0003-0393-5525","full_name":"Volosniev, Artem","last_name":"Volosniev"},{"first_name":"Abhishek","id":"5e9a6931-eb97-11eb-a6c2-e96f7058d77a","last_name":"Shiva Kumar","full_name":"Shiva Kumar, Abhishek"},{"full_name":"Lorenc, Dusan","last_name":"Lorenc","id":"40D8A3E6-F248-11E8-B48F-1D18A9856A87","first_name":"Dusan"},{"last_name":"Ashourishokri","full_name":"Ashourishokri, Younes","first_name":"Younes","id":"e32c111f-f6e0-11ea-865d-eb955baea334"},{"first_name":"Ayan A.","full_name":"Zhumekenov, Ayan A.","last_name":"Zhumekenov"},{"first_name":"Osman M.","full_name":"Bakr, Osman M.","last_name":"Bakr"},{"id":"37CB05FA-F248-11E8-B48F-1D18A9856A87","first_name":"Mikhail","full_name":"Lemeshko, Mikhail","orcid":"0000-0002-6990-7802","last_name":"Lemeshko"},{"last_name":"Alpichshev","full_name":"Alpichshev, Zhanybek","orcid":"0000-0002-7183-5203","id":"45E67A2A-F248-11E8-B48F-1D18A9856A87","first_name":"Zhanybek"}],"user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","citation":{"ista":"Volosniev A, Shiva Kumar A, Lorenc D, Ashourishokri Y, Zhumekenov AA, Bakr OM, Lemeshko M, Alpichshev Z. 2023.

A periodically kicked molecular rotor can be mapped onto a “crystalline” lattice in angular momentum space. This allows us to define quasimomenta and the band structure in the Floquet representation, by analogy with the Bloch waves of solid-state physics. Applying laser pulses spaced by 1/3 of the molecular rotational period creates a lattice with three atoms per unit cell with staggered hopping. Within the synthetic dimension of the laser strength, we discover Dirac cones with topological charges. These Dirac cones, topologically protected by reflection and time-reversal symmetry, are reminiscent of (although not equivalent to) that seen in graphene. They—and the corresponding edge states—are broadly tunable by adjusting the laser strength and can be observed in present-day experiments by measuring molecular alignment and populations of rotational levels. This paves the way to study controllable topological physics in gas-phase experiments with small molecules as well as to classify dynamical molecular states by their topological invariants."}],"intvolume":" 130","month":"03","main_file_link":[{"url":"https://doi.org/10.48550/arXiv.2206.07067","open_access":"1"}],"scopus_import":"1","language":[{"iso":"eng"}],"publication_status":"published","publication_identifier":{"issn":["0031-9007"],"eissn":["1079-7114"]},"ec_funded":1,"issue":"10","related_material":{"link":[{"relation":"press_release","url":"https://ista.ac.at/en/news/topology-of-rotating-molecules/","description":"News on the ISTA website"}]},"volume":130,"article_number":"103202","project":[{"_id":"2688CF98-B435-11E9-9278-68D0E5697425","call_identifier":"H2020","grant_number":"801770","name":"Angulon: physics and applications of a new quasiparticle"}],"user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","citation":{"mla":"Karle, Volker, et al. “Topological Charges of Periodically Kicked Molecules.” Physical Review Letters, vol. 130, no. 10, 103202, American Physical Society, 2023, doi:10.1103/PhysRevLett.130.103202.","apa":"Karle, V., Ghazaryan, A., & Lemeshko, M.

To this end, we study the density of states of multilayer graphene with up to four layers at the single-particle band structure level in the presence of a transverse electric field. Among the considered structures, tetralayer graphene with rhombohedral (ABCA) stacking reaches the highest density of states. We study the phases that can arise in ABCA graphene by tuning the carrier density and transverse electric field. For a broad region of the tuning parameters, the presence of strong Coulomb repulsion leads to a spontaneous spin and valley symmetry breaking via Stoner transitions. Using a model that incorporates the spontaneous spin and valley polarization, we explore the Kohn-Luttinger mechanism for superconductivity driven by repulsive Coulomb interactions. We find that the strongest superconducting instability is in the p-wave channel, and occurs in proximity to the onset of Stoner transitions. Interestingly, we find a range of densities and transverse electric fields where superconductivity develops out of a strongly corrugated, singly connected Fermi surface in each valley, leading to a topologically nontrivial chiral p+ip superconducting state with an even number of copropagating chiral Majorana edge modes. Our work establishes ABCA-stacked tetralayer graphene as a promising platform for observing strongly correlated physics and topological superconductivity."}],"related_material":{"link":[{"url":"https://ista.ac.at/en/news/reaching-superconductivity-layer-by-layer/","relation":"press_release","description":"News on the ISTA website"}]},"issue":"10","volume":107,"language":[{"iso":"eng"}],"publication_identifier":{"eissn":["2469-9969"],"issn":["2469-9950"]},"publication_status":"published","status":"public","article_type":"original","type":"journal_article","_id":"12790","department":[{"_id":"MaSe"},{"_id":"MiLe"}],"date_updated":"2023-08-01T13:59:29Z","publisher":"American Physical Society","quality_controlled":"1","oa":1,"acknowledgement":"E.B. and T.H. were supported by the European Research Council (ERC) under grant HQMAT (Grant Agreement No. 817799), by the Israel-USA Binational Science Foundation (BSF), and by a Research grant from Irving and Cherna Moskowitz.","doi":"10.1103/PhysRevB.107.104502","date_published":"2023-03-01T00:00:00Z","date_created":"2023-04-02T22:01:10Z","day":"01","publication":"Physical Review B","isi":1,"year":"2023","article_number":"104502","title":"Multilayer graphenes as a platform for interaction-driven physics and topological superconductivity","author":[{"id":"4AF46FD6-F248-11E8-B48F-1D18A9856A87","first_name":"Areg","last_name":"Ghazaryan","full_name":"Ghazaryan, Areg","orcid":"0000-0001-9666-3543"},{"full_name":"Holder, Tobias","last_name":"Holder","first_name":"Tobias"},{"first_name":"Erez","last_name":"Berg","full_name":"Berg, Erez"},{"id":"47809E7E-F248-11E8-B48F-1D18A9856A87","first_name":"Maksym","last_name":"Serbyn","orcid":"0000-0002-2399-5827","full_name":"Serbyn, Maksym"}],"external_id":{"isi":["000945526400003"],"arxiv":["2211.02492"]},"article_processing_charge":"No","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","citation":{"ieee":"A.

Here, we propose a coherent state ansatz in the co-rotating frame, which provides a comprehensive theoretical description of angulons. We reveal the quasiparticle properties, such as energies, quasiparticle weights, and spectral functions, and show that our ansatz yields a persistent decrease in the impurity’s rotational constant due to many-body dressing, which is consistent with experimental observations. From our study, a picture of the angulon emerges as an effective spin interacting with a magnetic field that is self-consistently generated by the molecule’s rotation. Moreover, we discuss rotational spectroscopy, which focuses on the response of rotating molecules to a laser perturbation in the linear response regime. Importantly, we take into account initial-state interactions that have been neglected in prior studies and reveal their impact on the excitation spectrum. To examine the angulon instability regime, we use a single-excitation ansatz and obtain results consistent with experiments, in which a broadening of spectral lines is observed while phonon wings remain highly suppressed due to initial-state interactions."}],"oa_version":"Published Version","scopus_import":"1","month":"04","intvolume":" 158","date_updated":"2023-08-01T14:08:47Z","ddc":["530"],"file_date_updated":"2023-04-17T07:28:38Z","department":[{"_id":"MiLe"}],"_id":"12831","article_type":"original","type":"journal_article","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)"},"status":"public","isi":1,"has_accepted_license":"1","year":"2023","day":"07","publication":"The Journal of Chemical Physics","date_published":"2023-04-07T00:00:00Z","doi":"10.1063/5.0135893","date_created":"2023-04-16T22:01:07Z","acknowledgement":"We thank Ignacio Cirac, Christian Schmauder, and Henrik Stapelfeldt for their valuable discussions.

In the conventional method using the Larmor clock, we show that the Larmor tunneling time can be shorter for higher tunneling barriers. In the second method, we study the probability of a spin-flip of a particle when it is transmitted through a potential barrier including a spatially rotating field interacting with its spin. According to the adiabatic theorem, the probability depends on the velocity of the particle inside the barrier. It is numerically observed that the probability increases for higher barriers, which is consistent with the result obtained by the Larmor clock. By comparing outcomes for different initial spin states, we suggest that one of the main causes of the apparent decrease in the tunneling time can be the filtering effect occurring at the end of the barrier."}],"oa_version":"Preprint","ec_funded":1,"issue":"4","volume":107,"publication_status":"published","publication_identifier":{"issn":["2469-9926"],"eissn":["2469-9934"]},"language":[{"iso":"eng"}],"article_type":"original","type":"journal_article","status":"public","_id":"12914","department":[{"_id":"MiLe"}],"date_updated":"2023-08-01T14:33:21Z","oa":1,"quality_controlled":"1","publisher":"American Physical Society","acknowledgement":"We thank W.

A key requirement for a comprehensive quantitative theory is the accurate determination of these materials' band structure parameters. However, this task is challenging due to the intricate band structures and the indirect nature of experimental probes. In this work, we introduce a general framework to derive band structure parameters from experimental data using deep neural networks. We applied our method to the penetration field capacitance measurement of trilayer graphene, an effective probe of its density of states. First, we demonstrate that a trained deep network gives accurate predictions for the penetration field capacitance as a function of tight-binding parameters. Next, we use the fast and accurate predictions from the trained network to automatically determine tight-binding parameters directly from experimental data, with extracted parameters being in a good agreement with values in the literature. We conclude by discussing potential applications of our method to other materials and experimental techniques beyond penetration field capacitance."}],"intvolume":" 108","month":"09","main_file_link":[{"open_access":"1","url":"https://doi.org/10.48550/arXiv.2210.06310"}],"scopus_import":"1","language":[{"iso":"eng"}],"publication_status":"published","publication_identifier":{"eissn":["2469-9969"],"issn":["2469-9950"]},"issue":"12","volume":108,"_id":"14320","status":"public","type":"journal_article","article_type":"original","date_updated":"2023-09-20T09:38:24Z","department":[{"_id":"MaSe"},{"_id":"ChLa"},{"_id":"MiLe"}]},{"day":"11","publication":"The Journal of Chemical Physics","has_accepted_license":"1","year":"2023","doi":"10.1063/5.0165806","date_published":"2023-09-11T00:00:00Z","date_created":"2023-09-13T09:25:09Z","acknowledgement":"We thank Zhanybek Alpichshev, Mohammad Reza Safari, Binghai Yan, and Yossi Paltiel for enlightening discussions.\r\nM.L. acknowledges support from the European Research Council (ERC) Starting Grant No. 801770 (ANGULON).

In this context, the robust valley degree of freedom and the associated valley pseudospin found in two-dimensional transition metal dichalcogenides is a highly attractive platform. Valley polarization and coherent superposition of valley states have been observed in these systems even up to room temperature. Control of valley coherence is an important building block for the implementation of valley qubit. Large magnetic fields or high-power lasers have been used in the past to demonstrate the control (initialization and rotation) of the valley coherent states. Here, the control of layer–valley coherence via strong coupling of valley excitons in bilayer WS2 to microcavity photons is demonstrated by exploiting the pseudomagnetic field arising in optical cavities owing to the transverse electric–transverse magnetic (TE–TM)mode splitting. The use of photonic structures to generate pseudomagnetic fields which can be used to manipulate exciton-polaritons presents an attractive approach to control optical responses without the need for large magnets or high-intensity optical pump powers."}],"oa_version":"Preprint","issue":"13","volume":11,"publication_identifier":{"eissn":["2195-1071"]},"publication_status":"published","language":[{"iso":"eng"}],"article_type":"original","type":"journal_article","status":"public","_id":"12836","department":[{"_id":"MiLe"}],"date_updated":"2023-10-04T11:15:17Z"},{"file_date_updated":"2023-08-14T07:43:45Z","department":[{"_id":"MiLe"}],"ddc":["530"],"date_updated":"2023-10-17T11:45:25Z","status":"public","article_type":"original","type":"journal_article","tmp":{"short":"CC BY-NC-ND (4.0)","name":"Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International (CC BY-NC-ND 4.0)","legal_code_url":"https://creativecommons.org/licenses/by-nc-nd/4.0/legalcode","image":"/images/cc_by_nc_nd.png"},"_id":"14037","issue":"32","volume":120,"license":"https://creativecommons.org/licenses/by-nc-nd/4.0/","ec_funded":1,"file":[{"creator":"dernst","date_updated":"2023-08-14T07:43:45Z","file_size":1003092,"date_created":"2023-08-14T07:43:45Z","file_name":"2023_PNAS_Vardi.pdf","access_level":"open_access","relation":"main_file","content_type":"application/pdf","file_id":"14047","checksum":"a5ed64788a5acef9b9a300a26fa5a177","success":1}],"language":[{"iso":"eng"}],"publication_identifier":{"eissn":["1091-6490"]},"publication_status":"published","month":"07","intvolume":" 120","scopus_import":"1","oa_version":"Published Version","pmid":1,"abstract":[{"text":"Traditionally, nuclear spin is not considered to affect biological processes. Recently, this has changed as isotopic fractionation that deviates from classical mass dependence was reported both in vitro and in vivo. In these cases, the isotopic effect correlates with the nuclear magnetic spin. Here, we show nuclear spin effects using stable oxygen isotopes (16O, 17O, and 18O) in two separate setups: an artificial dioxygen production system and biological aquaporin channels in cells. We observe that oxygen dynamics in chiral environments (in particular its transport) depend on nuclear spin, suggesting future applications for controlled isotope separation to be used, for instance, in NMR. To demonstrate the mechanism behind our findings, we formulate theoretical models based on a nuclear-spin-enhanced switch between electronic spin states. Accounting for the role of nuclear spin in biology can provide insights into the role of quantum effects in living systems and help inspire the development of future biotechnology solutions.","lang":"eng"}],"title":"Nuclear spin effects in biological processes","author":[{"first_name":"Ofek","full_name":"Vardi, Ofek","last_name":"Vardi"},{"first_name":"Naama","last_name":"Maroudas-Sklare","full_name":"Maroudas-Sklare, Naama"},{"first_name":"Yuval","last_name":"Kolodny","full_name":"Kolodny, Yuval"},{"full_name":"Volosniev, Artem","orcid":"0000-0003-0393-5525","last_name":"Volosniev","first_name":"Artem","id":"37D278BC-F248-11E8-B48F-1D18A9856A87"},{"full_name":"Saragovi, Amijai","last_name":"Saragovi","first_name":"Amijai"},{"first_name":"Nir","last_name":"Galili","full_name":"Galili, Nir"},{"first_name":"Stav","last_name":"Ferrera","full_name":"Ferrera, Stav"},{"first_name":"Areg","id":"4AF46FD6-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-9666-3543","full_name":"Ghazaryan, Areg","last_name":"Ghazaryan"},{"first_name":"Nir","last_name":"Yuran","full_name":"Yuran, Nir"},{"last_name":"Affek","full_name":"Affek, Hagit P.","first_name":"Hagit P."},{"first_name":"Boaz","last_name":"Luz","full_name":"Luz, Boaz"},{"last_name":"Goldsmith","full_name":"Goldsmith, Yonaton","first_name":"Yonaton"},{"last_name":"Keren","full_name":"Keren, Nir","first_name":"Nir"},{"last_name":"Yochelis","full_name":"Yochelis, Shira","first_name":"Shira"},{"full_name":"Halevy, Itay","last_name":"Halevy","first_name":"Itay"},{"id":"37CB05FA-F248-11E8-B48F-1D18A9856A87","first_name":"Mikhail","full_name":"Lemeshko, Mikhail","orcid":"0000-0002-6990-7802","last_name":"Lemeshko"},{"first_name":"Yossi","full_name":"Paltiel, Yossi","last_name":"Paltiel"}],"article_processing_charge":"Yes (in subscription journal)","external_id":{"pmid":["37523549"]},"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","citation":{"chicago":"Vardi, Ofek, Naama Maroudas-Sklare, Yuval Kolodny, Artem Volosniev, Amijai Saragovi, Nir Galili, Stav Ferrera, et al. “Nuclear Spin Effects in Biological Processes.” Proceedings of the National Academy of Sciences of the United States of America.

We demonstrate that short-ranged charge–rotor interactions lead to long-range ferroelectric ordering of rotors, which strongly affects the carrier mobility. In the nonperturbative regime, where our theory cannot be reduced to any of the earlier models, we reveal that the polaron is characterized by large coherence length and a roughly tenfold increase of the effective mass as compared to the bare mass. These results are in good agreement with other theoretical predictions for ferroelectric polarons. Our model establishes a general phenomenological framework for ferroelectric polarons providing the starting point for future studies of their role in the transport properties of hybrid organic-inorganic perovskites."}],"oa_version":"Published Version","file_date_updated":"2023-11-07T07:52:46Z","department":[{"_id":"MiLe"}],"date_updated":"2023-11-07T07:53:39Z","ddc":["530"],"tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)"},"type":"journal_article","article_type":"original","status":"public","_id":"14486"},{"oa":1,"quality_controlled":"1","publisher":"Elsevier","acknowledgement":"This review could not have been written without the many fruitful discussions and great collaborations with colleagues throughout the years, there are too many to mention.

The accelerating developments in the field have led to a highly advanced set of engineering techniques that, for example, can tune interactions, shape the external geometry, select among a large set of atomic species with different properties, or control the number of atoms. In particular, it is possible to operate in lower dimensions and drive atomic systems into the strongly correlated regime. In this review, we discuss recent advances in few-body cold atom systems confined in low dimensions from a theoretical viewpoint. We mainly focus on bosonic systems in one dimension and provide an introduction to the static properties before we review the state-of-the-art research into quantum dynamical processes stimulated by the presence of correlations. Besides discussing the fundamental physical phenomena arising in these systems, we also provide an overview of the calculational and numerical tools and methods that are commonly used, thus delivering a balanced and comprehensive overview of the field. We conclude by giving an outlook on possible future directions that are interesting to explore in these correlated systems.","lang":"eng"}],"oa_version":"Preprint","ec_funded":1,"volume":1042,"publication_status":"published","publication_identifier":{"issn":["0370-1573"]},"language":[{"iso":"eng"}],"type":"journal_article","article_type":"original","status":"public","_id":"14513","department":[{"_id":"MiLe"}],"date_updated":"2023-11-13T08:01:57Z"},{"status":"public","article_type":"original","type":"journal_article","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)"},"_id":"14658","file_date_updated":"2023-12-11T10:49:07Z","department":[{"_id":"MiLe"}],"ddc":["530"],"date_updated":"2023-12-11T10:55:52Z","month":"10","intvolume":" 5","scopus_import":"1","oa_version":"Published Version","abstract":[{"lang":"eng","text":"We investigate spin-charge separation of a spin-\r\n1\r\n2\r\n Fermi system confined in a triple well where multiple bands are occupied.

The typical formulation of the model is based upon a single particle picture, and should be extended when interactions with other particles become relevant. Here, we illustrate such an extension for a particle in an Aharonov-Bohm ring subject to interactions with a weakly interacting Bose gas. We show that the ground state of the system can be described using the Bose-polaron concept—a particle dressed by interactions with a bosonic environment. We connect the energy spectrum to the effective mass of the polaron, and demonstrate how to change currents in the system by tuning boson-particle interactions. Our results suggest the Aharonov-Bohm ring as a platform for studying coherence and few- to many-body crossover of quasi-particles that arise from an impurity immersed in a medium.","lang":"eng"}],"file_date_updated":"2023-09-05T08:45:49Z","department":[{"_id":"MiLe"}],"ddc":["530"],"date_updated":"2023-12-13T12:21:09Z","status":"public","keyword":["General Physics and Astronomy"],"type":"journal_article","article_type":"original","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)"},"_id":"14246"},{"publication_status":"published","publication_identifier":{"eissn":["1079-7114"],"issn":["0031-9007"]},"language":[{"iso":"eng"}],"ec_funded":1,"issue":"5","volume":131,"abstract":[{"lang":"eng","text":"We demonstrate that a sodium dimer, Na2(13Σ+u), residing on the surface of a helium nanodroplet, can be set into rotation by a nonresonant 1.0 ps infrared laser pulse.

Comparison to alignment dynamics calculated from the time-dependent rotational Schrödinger equation shows that the deviation is due to the alignment dependent interaction between the dimer and the droplet surface.

An impurity causes a rapid variation of the scattering phase shift for fermions at the Fermi surface, introducing a new characteristic length scale into the problem. We investigate manifestations of this length scale in the self-energy of the impurity and in the density of the bath. Our calculations reveal a model-independent deformation of the density of the Fermi gas, which is determined by the width of the resonance. To provide a broader picture, we investigate time evolution of the density in quench dynamics, and study the behavior of the system at finite temperatures.

Moreover, we derive the critical line that separates these regimes in the parameter space. In the thermodynamic limit, this critical line determines the maximum number of bosons that can be bound by the impurity potential, forming an artificial atom. Second, we validate the mean-field results using the flow equation approach and the multi-layer multi-configuration time-dependent Hartree method for atomic mixtures. While beyond-mean-field effects destroy long-range order in the Bose gas, the critical boson number is unaffected.

Rev. A 104 L061303). This calls for theoretical approaches that go beyond explaining renormalized values of molecular spectroscopic constants, which suffices when only the lowest few rotational states are involved. As the first step in this direction, here we present a basic quantum mechanical model describing highly excited rotational states of molecules in superfluid helium nanodroplets. We show that a linear molecule immersed in a superfluid can be seen as an effective symmetric top, similar to the rotational structure of radicals, such as OH or NO, but with the angular momentum of the superfluid playing the role of the electronic angular momentum in free molecules. The simple theory sheds light onto what happens when the rotational angular momentum of the molecule increases beyond the lowest excited states accessible by infrared spectroscopy. In addition, the model allows to estimate the effective rotational and centrifugal distortion constants for a broad range of species and to explain the crossover between light and heavy molecules in superfluid 4He in terms of the many-body wavefunction structure. Some of the above mentioned insights can be acquired by analyzing a simple 2 × 2 matrix.","lang":"eng"}],"file_date_updated":"2022-08-29T09:57:40Z","department":[{"_id":"MiLe"}],"ddc":["530"],"date_updated":"2023-08-03T13:19:06Z","status":"public","article_type":"original","type":"journal_article","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)"},"_id":"11998"},{"article_number":"023301","project":[{"grant_number":"M02641","name":"A path-integral approach to composite impurities","_id":"26986C82-B435-11E9-9278-68D0E5697425","call_identifier":"FWF"}],"citation":{"short":"G.

Taking the Fröhlich impurity model as a case study, we show that neural coherent states can learn the ground state of nonadditive systems very well. In particular, we recover exact diagonalization in all regimes tested and observe substantial improvement over the standard coherent state estimates in the most challenging intermediate-coupling regime.

We find that strain affects both Ir-Ir distance and Ir-O-Ir angle, and the rigid octahedra picture is not relevant. Second, we find fundamentally different behavior for compressive and tensile strain. One remarkable feature is the formation of two subsets of bond- and orbital-dependent carriers, a compass-like model, under compression. This originates from the strain-induced renormalization of the Ir-O-Ir superexchange and O on-site energy. We also show that under compressive (tensile) strain, Fermi surface becomes highly dispersive (relatively flat). Already at a tensile strain of 1.5%, we observe spectral weight redistribution, with the low-energy band acquiring almost purely singlet character.

In the superfluid phase, characterized by the spontaneous symmetry breaking of the U(1) symmetry, there is the coexistence of first and second sound. In the case of weakly-interacting repulsive bosons, we model the recent measurements of the sound velocities of 39K atoms in 2D obtained in the weakly-interacting regime and around the Berezinskii–Kosterlitz–Thouless (BKT) superfluid-to-normal transition temperature. In particular, we perform a quite accurate computation of the superfluid density and show that it is reasonably consistent with the experimental results. For superfluid attractive fermions, we calculate the first and second sound velocities across the whole BCS-BEC crossover. In the low-temperature regime, we reproduce the recent measurements of first-sound speed with 6Li atoms. We also predict that there is mixing between sound modes only in the finite-temperature BEC regime.","lang":"eng"}],"oa_version":"Published Version","scopus_import":"1","intvolume":" 14","month":"10","date_updated":"2023-08-09T10:13:17Z","ddc":["530"],"department":[{"_id":"MiLe"}],"file_date_updated":"2023-01-24T10:56:12Z","_id":"12154","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)"},"article_type":"original","type":"journal_article","keyword":["Physics and Astronomy (miscellaneous)","General Mathematics","Chemistry (miscellaneous)","Computer Science (miscellaneous)"],"status":"public"},{"project":[{"name":"International IST Doctoral Program","grant_number":"665385","call_identifier":"H2020","_id":"2564DBCA-B435-11E9-9278-68D0E5697425"}],"title":"Analytic and machine learning approaches to composite quantum impurities","author":[{"orcid":"0000-0002-1106-4419","full_name":"Rzadkowski, Wojciech","last_name":"Rzadkowski","first_name":"Wojciech","id":"48C55298-F248-11E8-B48F-1D18A9856A87"}],"article_processing_charge":"No","user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","citation":{"chicago":"Rzadkowski, Wojciech. “Analytic and Machine Learning Approaches to Composite Quantum Impurities.” Institute of Science and Technology Austria, 2022. https://doi.org/10.15479/at:ista:10759.","ista":"Rzadkowski W. 2022.

I exemplify this approach on the example of the polaron quasiparticle (Fröhlich Hamiltonian). In Chapter 5, I continue using artificial neural networks, albeit in a different setting. I apply artificial neural networks to detect phases from snapshots of two types physical systems.

It is known, however, that the geometry and topology of space can have significant effects on quantum statistics for particles moving on it. Here, we have undertaken the first step toward realizing the emerging fractional statistics for particles restricted to move on the sphere instead of on the plane. We show that such a model arises naturally in the context of quantum impurity problems. In particular, we demonstrate a setup in which the lowest-energy spectrum of two linear bosonic or fermionic molecules immersed in a quantum many-particle environment can coincide with the anyonic spectrum on the sphere. This paves the way toward the experimental realization of anyons on the sphere using molecular impurities. Furthermore, since a change in the alignment of the molecules corresponds to the exchange of the particles on the sphere, such a realization reveals a novel type of exclusion principle for molecular impurities, which could also be of use as a powerful technique to measure the statistics parameter. Finally, our approach opens up a simple numerical route to investigate the spectra of many anyons on the sphere. Accordingly, we present the spectrum of two anyons on the sphere in the presence of a Dirac monopole field."}],"oa_version":"Preprint","ec_funded":1,"volume":126,"related_material":{"record":[{"relation":"dissertation_contains","id":"12390","status":"public"}],"link":[{"url":"https://ist.ac.at/en/news/dancing-molecules-and-two-dimensional-particles/","relation":"press_release","description":"News on IST Homepage"}]},"issue":"1","publication_status":"published","publication_identifier":{"issn":["00319007"],"eissn":["10797114"]},"language":[{"iso":"eng"}],"project":[{"call_identifier":"H2020","_id":"2688CF98-B435-11E9-9278-68D0E5697425","grant_number":"801770","name":"Angulon: physics and applications of a new quasiparticle"}],"article_number":"015301","article_processing_charge":"No","external_id":{"arxiv":["2009.05948"],"isi":["000606325000003"]},"author":[{"orcid":"0000-0002-6249-0928","full_name":"Brooks, Morris","last_name":"Brooks","id":"B7ECF9FC-AA38-11E9-AC9A-0930E6697425","first_name":"Morris"},{"full_name":"Lemeshko, Mikhail","orcid":"0000-0002-6990-7802","last_name":"Lemeshko","first_name":"Mikhail","id":"37CB05FA-F248-11E8-B48F-1D18A9856A87"},{"full_name":"Lundholm, D.","last_name":"Lundholm","first_name":"D."},{"last_name":"Yakaboylu","full_name":"Yakaboylu, Enderalp","orcid":"0000-0001-5973-0874","first_name":"Enderalp","id":"38CB71F6-F248-11E8-B48F-1D18A9856A87"}],"title":"Molecular impurities as a realization of anyons on the two-sphere","citation":{"apa":"Brooks, M., Lemeshko, M., Lundholm, D., & Yakaboylu, E.

Here, for a two-dimensional system of ultracold fermions, we calculate the first and second sound velocities across the whole BCS-BEC crossover, and we analyze the system response to an external perturbation. In the low-temperature regime we reproduce the recent measurements [Phys. Rev. Lett. 124, 240403 (2020)] of the first sound velocity, which, due to the decoupling of density and entropy fluctuations, is the sole mode excited by a density probe. Conversely, a heat perturbation excites only the second sound, which, being sensitive to the superfluid depletion, vanishes in the deep BCS regime and jumps discontinuously to zero at the Berezinskii-Kosterlitz-Thouless superfluid transition. A mixing between the modes occurs only in the finite-temperature BEC regime, where our theory converges to the purely bosonic results."}],"oa_version":"Preprint","scopus_import":"1","main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/2009.06491"}],"month":"06","intvolume":" 103","date_updated":"2023-08-10T13:37:25Z","department":[{"_id":"MiLe"}],"_id":"9606","type":"journal_article","article_type":"letter_note","status":"public","isi":1,"year":"2021","day":"01","publication":"Physical Review A","doi":"10.1103/PhysRevA.103.L061303","date_published":"2021-06-01T00:00:00Z","date_created":"2021-06-27T22:01:49Z","acknowledgement":"G.B. acknowledges support from the Austrian Science Fund (FWF), under Project No. M2641-N27.

To set the stage, we first investigate the energy level distributions of the billiards as a function of 1/κ ∈ [0, 1] and find no evidence of integrable cases beyond the limiting values 1/κ = 1 and 1/κ = 0. Then, we use machine learning tools to analyze properties of probability distributions of individual quantum states. We find that convolutional neural networks can correctly classify integrable and non-integrable states. The decisive features of the wave functions are the normalization and a large number of zero elements, corresponding to the existence of a nodal line. The network achieves typical accuracies of 97%, suggesting that machine learning tools can be used to analyze and classify the morphology of probability densities obtained in theory or experiment.","lang":"eng"}],"ec_funded":1,"volume":23,"issue":"6","language":[{"iso":"eng"}],"file":[{"access_level":"open_access","relation":"main_file","content_type":"application/pdf","file_id":"9690","checksum":"e39164ce7ea228d287cf8924e1a0f9fe","success":1,"creator":"cziletti","date_updated":"2021-07-19T11:47:16Z","file_size":3868445,"date_created":"2021-07-19T11:47:16Z","file_name":"2021_NewJPhys_Huber.pdf"}],"publication_status":"published","publication_identifier":{"eissn":["13672630"]},"status":"public","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)"},"article_type":"original","type":"journal_article","_id":"9679","department":[{"_id":"MiLe"}],"file_date_updated":"2021-07-19T11:47:16Z","ddc":["530"],"date_updated":"2023-08-10T13:58:09Z"},{"oa_version":"Preprint","abstract":[{"text":"We study an effective one-dimensional quantum model that includes friction and spin-orbit coupling (SOC), and show that the model exhibits spin polarization when both terms are finite.

For a single mobile impurity, we use flow equations to validate the mean-field results obtained upon the Lee-Low-Pines transformation. We show that the mean-field approximation is accurate for all values of the boson-impurity interaction strength as long as the phase coherence length is much larger than the healing length of the condensate. For two static impurities, we calculate impurity-impurity interactions induced by the Bose gas. We find that leading order perturbation theory fails when boson-impurity interactions are stronger than boson-boson interactions.

Identifying systems where at least some eigenstates are nonthermal is an outstanding question. In this Letter we show that interacting quantum models that have a nullspace—a degenerate subspace of eigenstates at zero energy (zero modes), which corresponds to infinite temperature, provide a route to nonthermal eigenstates. We analytically show the existence of a zero mode which can be represented as a matrix product state for a certain class of local Hamiltonians. In the more general case we use a subspace disentangling algorithm to generate an orthogonal basis of zero modes characterized by increasing entanglement entropy. We show evidence for an area-law entanglement scaling of the least-entangled zero mode in the broad parameter regime, leading to a conjecture that all local Hamiltonians with the nullspace feature zero modes with area-law entanglement scaling and, as such, break the strong thermalization hypothesis. Finally, we find zero modes in constrained models and propose a setup for observing their experimental signatures."}],"oa_version":"Published Version","volume":127,"issue":"6","ec_funded":1,"publication_identifier":{"issn":["0031-9007"],"eissn":["1079-7114"]},"publication_status":"published","file":[{"content_type":"application/pdf","relation":"main_file","access_level":"open_access","success":1,"file_id":"9904","checksum":"51218f302dcef99d90d1209809fcc874","file_size":5064231,"date_updated":"2021-08-13T09:28:08Z","creator":"mserbyn","file_name":"PhysRevLett.127.060602_SOM.pdf","date_created":"2021-08-13T09:28:08Z"}],"language":[{"iso":"eng"}],"project":[{"_id":"23841C26-32DE-11EA-91FC-C7463DDC885E","call_identifier":"H2020","name":"Non-Ergodic Quantum Matter: Universality, Dynamics and Control","grant_number":"850899"}],"article_number":"060602","author":[{"first_name":"Volker","id":"D7C012AE-D7ED-11E9-95E8-1EC5E5697425","last_name":"Karle","orcid":"0000-0002-6963-0129","full_name":"Karle, Volker"},{"id":"47809E7E-F248-11E8-B48F-1D18A9856A87","first_name":"Maksym","last_name":"Serbyn","full_name":"Serbyn, Maksym","orcid":"0000-0002-2399-5827"},{"id":"36EBAD38-F248-11E8-B48F-1D18A9856A87","first_name":"Alexios","full_name":"Michailidis, Alexios","orcid":"0000-0002-8443-1064","last_name":"Michailidis"}],"article_processing_charge":"Yes (in subscription journal)","external_id":{"isi":["000684276000002"],"arxiv":["2102.13633"]},"title":"Area-law entangled eigenstates from nullspaces of local Hamiltonians","citation":{"ieee":"V.

Here we show that gate-tuned van Hove singularities in rhombohedral trilayer graphene drive the spontaneous ferromagnetic polarization of the electron system into one or more spin- and valley flavors. Using capacitance measurements on graphite-gated van der Waals heterostructures, we find a cascade of density- and electronic displacement field tuned phase transitions marked by negative electronic compressibility. The transitions define the boundaries between phases where quantum oscillations have either four-fold, two-fold, or one-fold degeneracy, associated with a spin and valley degenerate normal metal, spin-polarized `half-metal', and spin and valley polarized `quarter metal', respectively. For electron doping, the salient features are well captured by a phenomenological Stoner model with a valley-anisotropic Hund's coupling, likely arising from interactions at the lattice scale. For hole filling, we observe a richer phase diagram featuring a delicate interplay of broken symmetries and transitions in the Fermi surface topology. Finally, by rotational alignment of a hexagonal boron nitride substrate to induce a moiré superlattice, we find that the superlattice perturbs the preexisting isospin order only weakly, leaving the basic phase diagram intact while catalyzing the formation of topologically nontrivial gapped states whenever itinerant half- or quarter metal states occur at half- or quarter superlattice band filling. Our results show that rhombohedral trilayer graphene is an ideal platform for well-controlled tests of many-body theory and reveal magnetism in moiré materials to be fundamentally itinerant in nature."}],"oa_version":"Preprint","scopus_import":"1","main_file_link":[{"url":"https://arxiv.org/abs/2104.00653","open_access":"1"}],"month":"09","date_updated":"2023-08-14T07:04:06Z","department":[{"_id":"MaSe"},{"_id":"MiLe"}],"_id":"10025","article_type":"original","type":"journal_article","status":"public","keyword":["condensed matter - mesoscale and nanoscale physics","condensed matter - strongly correlated electrons","multidisciplinary"],"isi":1,"year":"2021","day":"01","publication":"Nature","doi":"10.1038/s41586-021-03938-w","date_published":"2021-09-01T00:00:00Z","date_created":"2021-09-19T22:01:25Z","acknowledgement":"The authors acknowledge discussions with A.

Second, we show the existence of a spin current in a system with a temperature difference by studying the dynamics that follows the spin-flip of an atom in the link.

In contrast, we find that topological Kondo insulators (TKIs) can support surface states with an arbitrarily large Fermi surface (FS) when the chemical potential is pinned to the Dirac point. We illustrate that these FSs give rise to finite-frequency QOs, which can become comparable to the extremal area of the unhybridized bulk bands. We show that this occurs when the crystal symmetry is lowered from cubic to tetragonal in a minimal two-orbital model. We label such surface modes as 'shadow surface states'. Moreover, we show that the sufficient next-nearest neighbor out-of-plane hybridization leading to shadow surface states can be self-consistently stabilized for tetragonal TKIs. Consequently, shadow surface states provide an important example of high-frequency QOs beyond the context of cubic TKIs."}],"intvolume":" 23","month":"12","scopus_import":"1","language":[{"iso":"eng"}],"file":[{"file_name":"2021_NewJourPhys_Ghazaryan.pdf","date_created":"2022-01-17T10:01:58Z","file_size":2533102,"date_updated":"2022-01-17T10:01:58Z","creator":"cchlebak","success":1,"checksum":"0c3cb6816242fa8afd1cc87a5fe77821","file_id":"10632","content_type":"application/pdf","relation":"main_file","access_level":"open_access"}],"publication_status":"published","publication_identifier":{"issn":["1367-2630"]},"ec_funded":1,"issue":"12","volume":23},{"oa":1,"publisher":"American Physical Society","quality_controlled":"1","acknowledgement":"I.C. acknowledges the support by the European Union’s Horizon 2020 research and innovation programme under the Marie Sklodowska-Curie Grant Agreement No. 665385.

We construct a simple quantum-mechanical model, based on a linear rotor coupled to a single-mode bosonic bath, to determine the rotational energy structure in its entirety. The calculated and measured spectral lines are in good agreement.

So far, however, it has proven challenging to deal with microscopic models in which the total number of particles is not conserved. To address this issue, we propose a new variant of neural network states, which we term neural coherent states. Taking the Fröhlich impurity model as a case study, we show that neural coherent states can learn the ground state of non-additive systems very well. In particular, we observe substantial improvement over the standard coherent state estimates in the most challenging intermediate coupling regime. Our approach is generic and does not assume specific details of the system, suggesting wide applications.","lang":"eng"}],"oa_version":"Preprint","acknowledgement":"We acknowledge fruitful discussions with Giacomo Bighin, Giammarco Fabiani, Areg Ghazaryan, Christoph\r\nLampert, and Artem Volosniev at various stages of this work.

Spin-orbit coupling, combined with the proximity effect, causes the two-dimensional semiconductor to inherit p±ip intraband pairing, and application of magnetic field can then result in transitions to the normal state, partial Bogoliubov Fermi surfaces, or topological phases with Majorana modes. Experimentally probing the hybrid superconductor-semiconductor interface is challenging due to the shunting effect of the conventional superconductor. Consequently, the nature of induced pairing remains an open question. Here, we use the circuit quantum electrodynamics architecture to probe induced superconductivity in a two dimensional Al-InAs hybrid system. We observe a strong suppression of superfluid density and enhanced dissipation driven by magnetic field, which cannot be accounted for by the depairing theory of an s-wave superconductor. These observations are explained by a picture of independent intraband p±ip superconductors giving way to partial Bogoliubov Fermi surfaces, and allow for the first characterization of key properties of the hybrid superconducting system."}],"acknowledgement":"This research was supported by the Scientific Service Units of IST Austria through resources provided by the MIBA Machine Shop and the nanofabrication facility.

We investigate how the spin-orbital entanglement in a Mott insulator depends on the value of the spin-orbit coupling of the relativistic origin. To this end, we numerically diagonalize a one-dimensional spin-orbital model with Kugel-Khomskii exchange interactions between spins and orbitals on different sites supplemented by the on-site spin-orbit coupling. In the regime of small spin-orbit coupling with regard to the spin-orbital exchange, the ground state to a large extent resembles the one obtained in the limit of vanishing spin-orbit coupling. On the other hand, for large spin-orbit coupling the ground state can, depending on the model parameters, either still show negligible spin-orbital entanglement or evolve to a highly spin-orbitally-entangled phase with completely distinct properties that are described by an effective XXZ model. The presented results suggest that (i) the spin-orbital entanglement may be induced by large on-site spin-orbit coupling, as found in the 5d transition metal oxides, such as the iridates; (ii) for Mott insulators with weak spin-orbit coupling of Ising type, such as, e.g., the alkali hyperoxides, the effects of the spin-orbit coupling on the ground state can, in the first order of perturbation theory, be neglected."}],"oa_version":"Published Version","intvolume":" 2","month":"03","date_updated":"2021-01-12T08:14:23Z","ddc":["530"],"file_date_updated":"2020-07-14T12:48:00Z","department":[{"_id":"MiLe"}],"_id":"7594","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)"},"article_type":"original","type":"journal_article","status":"public"},{"citation":{"chicago":"Mistakidis, S.

The input for our calculations—the energies of few-body clusters—is estimated using the harmonic approximation. We first describe and demonstrate the validity of our numerical procedure.

For temperature higher than its binding energy threshold, the dimers overwhelmingly dominate the ensemble, where the remaining probability is in free particles. At very high temperatures free (harmonic oscillator trap-bound) particle dominance is eventually reached.

We interpret the coupling as a phonon-mediated spin-orbit coupling and quantify it by using a correlation function between the internal and the orbital angular momentum operators. The strong-coupling regime is investigated within the Pekar approach, and it is shown that the correlation function of the ground state shows a kink at a critical coupling, that is explained by a sharp transition from the noninteracting state to the states that exhibit strong interaction with the surroundings.

In certain applications, it is important to filter electrons with one spin projection from the rest. Such filtering is not trivial, since spin-dependent interactions are often weak, and cannot lead to any substantial effect. Here we propose an efficient spin filter based upon scattering from a two-dimensional crystal, which is made of aligned point magnets. The polarization of the outgoing electron flux is controlled by the crystal, and reaches maximum at specific values of the parameters. In our scheme, polarization increase is accompanied by higher reflectivity of the crystal. High transmission is feasible in scattering from a quantum cavity made of two crystals. Our findings can be used for studies of low-energy spin-dependent scattering from two-dimensional ordered structures made of magnetic atoms or aligned chiral molecules.","lang":"eng"}],"oa_version":"Published Version"},{"ddc":["530"],"date_updated":"2023-08-22T12:11:52Z","department":[{"_id":"MiLe"}],"file_date_updated":"2020-10-28T11:53:12Z","_id":"8699","status":"public","type":"journal_article","article_type":"original","tmp":{"short":"CC BY-NC-ND (4.0)","name":"Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International (CC BY-NC-ND 4.0)","legal_code_url":"https://creativecommons.org/licenses/by-nc-nd/4.0/legalcode","image":"/images/cc_by_nc_nd.png"},"file":[{"date_created":"2020-10-28T11:53:12Z","file_name":"2020_PNAS_Paris.pdf","creator":"cziletti","date_updated":"2020-10-28T11:53:12Z","file_size":1176522,"checksum":"1638fa36b442e2868576c6dd7d6dc505","file_id":"8715","success":1,"access_level":"open_access","relation":"main_file","content_type":"application/pdf"}],"language":[{"iso":"eng"}],"publication_identifier":{"eissn":["10916490"],"issn":["00278424"]},"publication_status":"published","volume":117,"issue":"40","ec_funded":1,"pmid":1,"oa_version":"Published Version","abstract":[{"text":"In the high spin–orbit-coupled Sr2IrO4, the high sensitivity of the ground state to the details of the local lattice structure shows a large potential for the manipulation of the functional properties by inducing local lattice distortions. We use epitaxial strain to modify the Ir–O bond geometry in Sr2IrO4 and perform momentum-dependent resonant inelastic X-ray scattering (RIXS) at the metal and at the ligand sites to unveil the response of the low-energy elementary excitations. We observe that the pseudospin-wave dispersion for tensile-strained Sr2IrO4 films displays large softening along the [h,0] direction, while along the [h,h] direction it shows hardening. This evolution reveals a renormalization of the magnetic interactions caused by a strain-driven cross-over from anisotropic to isotropic interactions between the magnetic moments. Moreover, we detect dispersive electron–hole pair excitations which shift to lower (higher) energies upon compressive (tensile) strain, manifesting a reduction (increase) in the size of the charge gap. This behavior shows an intimate coupling between charge excitations and lattice distortions in Sr2IrO4, originating from the modified hopping elements between the t2g orbitals. Our work highlights the central role played by the lattice degrees of freedom in determining both the pseudospin and charge excitations of Sr2IrO4 and provides valuable information toward the control of the ground state of complex oxides in the presence of high spin–orbit coupling.","lang":"eng"}],"month":"10","intvolume":" 117","scopus_import":"1","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","citation":{"ista":"Paris E, Tseng Y, Paerschke E, Zhang W, Upton MH, Efimenko A, Rolfs K, McNally DE, Maurel L, Naamneh M, Caputo M, Strocov VN, Wang Z, Casa D, Schneider CW, Pomjakushina E, Wohlfeld K, Radovic M, Schmitt T. 2020.

From that perspective, chiral molecules acting as efficient spin selectors pose a puzzle that attracted a lot of attention in recent years. Here, we revisit the physical origins of chiral-induced spin selectivity (CISS) and propose a simple analytic minimal model to describe it. The model treats a chiral molecule as an anisotropic wire with molecular dipole moments aligned arbitrarily with respect to the wire’s axes and is therefore quite general. Importantly, it shows that the helical structure of the molecule is not necessary to observe CISS and other chiral nonhelical molecules can also be considered as potential candidates for the CISS effect. We also show that the suggested simple model captures the main characteristics of CISS observed in the experiment, without the need for additional constraints employed in the previous studies. The results pave the way for understanding other related physical phenomena where the CISS effect plays an essential role."}],"oa_version":"Published Version","scopus_import":"1","month":"05","intvolume":" 124","date_updated":"2023-09-05T12:07:15Z","ddc":["530"],"file_date_updated":"2020-10-20T14:39:47Z","department":[{"_id":"MiLe"}],"_id":"7968","type":"journal_article","article_type":"original","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)"},"status":"public","has_accepted_license":"1","isi":1,"year":"2020","day":"04","publication":"The Journal of Physical Chemistry C","page":"11716-11721","date_published":"2020-05-04T00:00:00Z","doi":"10.1021/acs.jpcc.0c02584","date_created":"2020-06-16T14:29:59Z","quality_controlled":"1","publisher":"American Chemical Society","oa":1,"citation":{"chicago":"Ghazaryan, Areg, Yossi Paltiel, and Mikhail Lemeshko. “Analytic Model of Chiral-Induced Spin Selectivity.” The Journal of Physical Chemistry C.

Here, we theoretically study interactions between IXs in stacked DQW bilayers, where the dipolar coupling can be either attractive or repulsive depending on the relative positions of the particles. By using microscopic band structure calculations to determine the electronic states forming the excitons, we show that the attractive dipolar interaction between stacked IXs deforms their electronic wave function, thereby increasing the inter-DQW interaction energy and making the IX even more electrically polarizable. Many-particle interaction effects are addressed by considering the coupling between a single IX in one of the DQWs to a cloud of IXs in the other DQW, which is modeled either as a closed-packed lattice or as a continuum IX fluid. We find that the lattice model yields IX interlayer binding energies decreasing with increasing lattice density. This behavior is due to the dominating role of the intra-DQW dipolar repulsion, which prevents more than one exciton from entering the attractive region of the inter-DQW coupling. Finally, both models shows that the single IX distorts the distribution of IXs in the adjacent DQW, thus inducing the formation of an IX dipolar polaron (dipolaron). While the interlayer binding energy reduces with IX density for lattice dipolarons, the continuous polaron model predicts a nonmonotonous dependence on density in semiquantitative agreement with a recent experimental study [cf.

Although anyons are predicted to be realized in certain fractional quantum Hall systems, they have not yet been unambiguously detected in experiment. Here we introduce a simple quantum impurity model, where bosonic or fermionic impurities turn into anyons as a consequence of their interaction with the surrounding many-particle bath. A cloud of phonons dresses each impurity in such a way that it effectively attaches fluxes or vortices to it and thereby converts it into an Abelian anyon. The corresponding quantum impurity model, first, provides a different approach to the numerical solution of the many-anyon problem, along with a concrete perspective of anyons as emergent quasiparticles built from composite bosons or fermions. More importantly, the model paves the way toward realizing anyons using impurities in crystal lattices as well as ultracold gases. In particular, we consider two heavy electrons interacting with a two-dimensional lattice crystal in a magnetic field, and show that when the impurity-bath system is rotated at the cyclotron frequency, impurities behave as anyons as a consequence of the angular momentum exchange between the impurities and the bath. A possible experimental realization is proposed by identifying the statistics parameter in terms of the mean-square distance of the impurities and the magnetization of the impurity-bath system, both of which are accessible to experiment. Another proposed application is impurities immersed in a two-dimensional weakly interacting Bose gas."}],"oa_version":"Preprint","scopus_import":"1","main_file_link":[{"url":"https://arxiv.org/abs/1912.07890","open_access":"1"}],"month":"10","intvolume":" 102"},{"author":[{"last_name":"Li","full_name":"Li, Xiang","id":"4B7E523C-F248-11E8-B48F-1D18A9856A87","first_name":"Xiang"},{"id":"38CB71F6-F248-11E8-B48F-1D18A9856A87","first_name":"Enderalp","last_name":"Yakaboylu","orcid":"0000-0001-5973-0874","full_name":"Yakaboylu, Enderalp"},{"last_name":"Bighin","full_name":"Bighin, Giacomo","orcid":"0000-0001-8823-9777","first_name":"Giacomo","id":"4CA96FD4-F248-11E8-B48F-1D18A9856A87"},{"first_name":"Richard","full_name":"Schmidt, Richard","last_name":"Schmidt"},{"id":"37CB05FA-F248-11E8-B48F-1D18A9856A87","first_name":"Mikhail","last_name":"Lemeshko","full_name":"Lemeshko, Mikhail","orcid":"0000-0002-6990-7802"},{"id":"4DA65CD0-F248-11E8-B48F-1D18A9856A87","first_name":"Andreas","last_name":"Deuchert","full_name":"Deuchert, Andreas","orcid":"0000-0003-3146-6746"}],"external_id":{"arxiv":["1912.02658"],"isi":["000530448300001"]},"article_processing_charge":"No","title":"Intermolecular forces and correlations mediated by a phonon bath","citation":{"mla":"Li, Xiang, et al. “Intermolecular Forces and Correlations Mediated by a Phonon Bath.” The Journal of Chemical Physics, vol. 152, no. 16, 164302, AIP Publishing, 2020, doi:10.1063/1.5144759.","ama":"Li X, Yakaboylu E, Bighin G, Schmidt R, Lemeshko M, Deuchert A.

By analogy with the bipolaron, we introduce the biangulon quasiparticle describing two rotating molecules that align with respect to each other due to the effective attractive interaction mediated by the excitations of the bath. We study this system in different parameter regimes and apply several theoretical approaches to describe its properties. Using a Born–Oppenheimer approximation, we investigate the dependence of the effective intermolecular interaction on the rotational state of the two molecules. In the strong-coupling regime, a product-state ansatz shows that the molecules tend to have a strong alignment in the ground state. To investigate the system in the weak-coupling regime, we apply a one-phonon excitation variational ansatz, which allows us to access the energy spectrum. In comparison to the angulon quasiparticle, the biangulon shows shifted angulon instabilities and an additional spectral instability, where resonant angular momentum transfer between the molecules and the bath takes place. These features are proposed as an experimentally observable signature for the formation of the biangulon quasiparticle. Finally, by using products of single angulon and bare impurity wave functions as basis states, we introduce a diagonalization scheme that allows us to describe the transition from two separated angulons to a biangulon as a function of the distance between the two molecules.","lang":"eng"}],"oa_version":"Preprint"},{"project":[{"_id":"2564DBCA-B435-11E9-9278-68D0E5697425","call_identifier":"H2020","name":"International IST Doctoral Program","grant_number":"665385"},{"_id":"05A235A0-7A3F-11EA-A408-12923DDC885E","grant_number":"25681","name":"Analytic and machine learning approaches to composite quantum impurities"},{"_id":"26986C82-B435-11E9-9278-68D0E5697425","call_identifier":"FWF","name":"A path-integral approach to composite impurities","grant_number":"M02641"}],"article_number":"093026","title":"Detecting composite orders in layered models via machine learning","external_id":{"isi":["000573298000001"]},"article_processing_charge":"No","author":[{"full_name":"Rzadkowski, Wojciech","orcid":"0000-0002-1106-4419","last_name":"Rzadkowski","first_name":"Wojciech","id":"48C55298-F248-11E8-B48F-1D18A9856A87"},{"first_name":"N","last_name":"Defenu","full_name":"Defenu, N"},{"full_name":"Chiacchiera, S","last_name":"Chiacchiera","first_name":"S"},{"last_name":"Trombettoni","full_name":"Trombettoni, A","first_name":"A"},{"orcid":"0000-0001-8823-9777","full_name":"Bighin, Giacomo","last_name":"Bighin","first_name":"Giacomo","id":"4CA96FD4-F248-11E8-B48F-1D18A9856A87"}],"user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","citation":{"mla":"Rzadkowski, Wojciech, et al. “Detecting Composite Orders in Layered Models via Machine Learning.” New Journal of Physics, vol. 22, no. 9, 093026, IOP Publishing, 2020, doi:10.1088/1367-2630/abae44.","ieee":"W.

A general question is whether new phases, not present in the uncoupled limit, may arise. We use machine learning and a suitable quasidistance between different points of the phase diagram to study layered spin models, in which the spin variables constituting each of the uncoupled systems (to which we refer as layers) are coupled to each other via an interlayer coupling. In such systems, in general, composite order parameters involving spins of different layers may emerge as a consequence of the interlayer coupling. We focus on the layered Ising and Ashkin–Teller models as a paradigmatic case study, determining their phase diagram via the application of a machine learning algorithm to the Monte Carlo data. Remarkably our technique is able to correctly characterize all the system phases also in the case of hidden order parameters, i.e. order parameters whose expression in terms of the microscopic configurations would require additional preprocessing of the data fed to the algorithm. We correctly retrieve the three known phases of the Ashkin–Teller model with ferromagnetic couplings, including the phase described by a composite order parameter. For the bilayer and trilayer Ising models the phases we find are only the ferromagnetic and the paramagnetic ones. Within the approach we introduce, owing to the construction of convolutional neural networks, naturally suitable for layered image-like data with arbitrary number of layers, no preprocessing of the Monte Carlo data is needed, also with regard to its spatial structure. The physical meaning of our results is discussed and compared with analytical data, where available. Yet, the method can be used without any a priori knowledge of the phases one seeks to find and can be applied to other models and structures."}],"ec_funded":1,"related_material":{"record":[{"id":"10759","status":"public","relation":"dissertation_contains"}]},"issue":"9","volume":22,"language":[{"iso":"eng"}],"file":[{"file_size":2725143,"date_updated":"2020-10-12T12:18:47Z","creator":"dernst","file_name":"2020_NewJournalPhysics_Rzdkowski.pdf","date_created":"2020-10-12T12:18:47Z","content_type":"application/pdf","relation":"main_file","access_level":"open_access","success":1,"file_id":"8650","checksum":"c9238fff422e7a957c3a0d559f756b3a"}],"publication_status":"published","publication_identifier":{"issn":["13672630"]}},{"abstract":[{"text":"The oft-quoted dictum by Arthur Schawlow: ``A diatomic molecule has one atom too many'' has been disavowed. Inspired by the possibility to experimentally manipulate and enhance chemical reactivity in helium nanodroplets, we investigate the rotation of coupled cold molecules in the presence of a many-body environment.\r\nIn this thesis, we introduce new variational approaches to quantum impurities and apply them to the Fröhlich polaron - a quasiparticle formed out of an electron (or other point-like impurity) in a polar medium, and to the angulon - a quasiparticle formed out of a rotating molecule in a bosonic bath.\r\nWith this theoretical toolbox, we reveal the self-localization transition for the angulon quasiparticle. We show that, unlike for polarons, self-localization of angulons occurs at finite impurity-bath coupling already at the mean-field level. The transition is accompanied by the spherical-symmetry breaking of the angulon ground state and a discontinuity in the first derivative of the ground-state energy. Moreover, the type of symmetry breaking is dictated by the symmetry of the microscopic impurity-bath interaction, which leads to a number of distinct self-localized states. \r\nFor the system containing multiple impurities, by analogy with the bipolaron, we introduce the biangulon quasiparticle describing two rotating molecules that align with respect to each other due to the effective attractive interaction mediated by the excitations of the bath. We study this system from the strong-coupling regime to the weak molecule-bath interaction regime. We show that the molecules tend to have a strong alignment in the ground state, the biangulon shows shifted angulon instabilities and an additional spectral instability, where resonant angular momentum transfer between the molecules and the bath takes place. Finally, we introduce a diagonalization scheme that allows us to describe the transition from two separated angulons to a biangulon as a function of the distance between the two molecules.","lang":"eng"}],"oa_version":"Published Version","alternative_title":["ISTA Thesis"],"month":"12","publication_status":"published","degree_awarded":"PhD","publication_identifier":{"issn":["2663-337X"]},"language":[{"iso":"eng"}],"file":[{"relation":"main_file","access_level":"open_access","content_type":"application/pdf","success":1,"file_id":"8967","checksum":"3994c54a1241451d561db1d4f43bad30","creator":"xli","file_size":3622305,"date_updated":"2020-12-22T10:55:56Z","file_name":"THESIS_Xiang_Li.pdf","date_created":"2020-12-22T10:55:56Z"},{"file_name":"THESIS_Xiang_Li.zip","date_created":"2020-12-22T10:56:03Z","file_size":4018859,"date_updated":"2020-12-30T07:18:03Z","creator":"xli","file_id":"8968","checksum":"0954ecfc5554c05615c14de803341f00","content_type":"application/x-zip-compressed","relation":"source_file","access_level":"closed"}],"ec_funded":1,"related_material":{"record":[{"relation":"part_of_dissertation","id":"5886","status":"public"},{"id":"8587","status":"public","relation":"part_of_dissertation"},{"status":"public","id":"1120","relation":"part_of_dissertation"}]},"_id":"8958","type":"dissertation","status":"public","date_updated":"2023-09-20T11:30:58Z","supervisor":[{"first_name":"Mikhail","id":"37CB05FA-F248-11E8-B48F-1D18A9856A87","full_name":"Lemeshko, Mikhail","orcid":"0000-0002-6990-7802","last_name":"Lemeshko"}],"ddc":["539"],"department":[{"_id":"MiLe"}],"file_date_updated":"2020-12-30T07:18:03Z","oa":1,"publisher":"Institute of Science and Technology Austria","year":"2020","has_accepted_license":"1","day":"21","page":"125","date_created":"2020-12-21T09:44:30Z","doi":"10.15479/AT:ISTA:8958","date_published":"2020-12-21T00:00:00Z","project":[{"grant_number":"P29902","name":"Quantum rotations in the presence of a many-body environment","call_identifier":"FWF","_id":"26031614-B435-11E9-9278-68D0E5697425"},{"name":"Angulon: physics and applications of a new quasiparticle","grant_number":"801770","_id":"2688CF98-B435-11E9-9278-68D0E5697425","call_identifier":"H2020"}],"citation":{"apa":"Li, X.

To understand their origin, we examine the interplay of Zeeman coupling and superconducting pairings in three-dimensional metals with band inversion. Weak Zeeman fields are found to suppress intraorbital spin-singlet pairing, known to localize the states at the ends of the vortices on the surface. On the other hand, an orbital-triplet pairing is shown to be stable against Zeeman interactions, but leads to delocalized zero-energy Majorana modes which extend through the vortex. In contrast, the finite-energy vortex modes remain localized at the vortex ends even when the pairing is of orbital-triplet form. Phenomenologically, this manifests as an observed disappearance of zero-bias peaks within the cores of topological vortices upon an increase of the applied magnetic field. The presence of magnetic impurities in FeTe(1−x)Sex, which are attracted to the vortices, would lead to such Zeeman-induced delocalization of Majorana modes in a fraction of vortices that capture a large enough number of magnetic impurities.

Complex interactions exist between tipping elements, e.g. physical mechanisms connect subsystems of the climate system. Based on earlier work on such coupled nonlinear systems, we systematically assessed the qualitative long-term behaviour of interacting tipping elements. We developed an understanding of the consequences of interactions\r\non the tipping behaviour allowing for tipping cascades to emerge under certain conditions. The (narrative) application of\r\nthese qualitative results to real-world examples of interacting tipping elements indicates that tipping cascades with profound consequences may occur: the interacting Greenland ice sheet and thermohaline ocean circulation might tip before the tipping points of the isolated subsystems are crossed. The eutrophication of the first lake in a lake chain might propagate through the following lakes without a crossing of their individual critical nutrient input levels.

We consider spinless fermions with no fermion-fermion interactions. The fermion-impurity and impurity-impurity interactions are modeled with Dirac delta functions. First, we study the case where impurity and fermion have equal masses, and the impurity-impurity two-body interaction is identical to the fermion-impurity interaction, such that the system is solvable with the Bethe ansatz. For attractive interactions, we find that the energy of the impurity-impurity subsystem is below the energy of the bound state that exists without the Fermi gas. We interpret this as a manifestation of attractive boson-boson interactions induced by the fermionic medium, and refer to the impurity-impurity subsystem as an in-medium bound state. For repulsive interactions, we find no in-medium bound states. Second, we construct an effective model to describe these interactions, and compare its predictions to the exact solution. We use this effective model to study nonintegrable systems with unequal masses and/or potentials. We discuss parameter regimes for which impurity-impurity attraction induced by the Fermi gas can lead to the formation of in-medium bound states made of bosons that repel each other in the absence of the Fermi gas.","lang":"eng"}],"oa_version":"Published Version","volume":1,"issue":"3","ec_funded":1,"publication_identifier":{"issn":["2643-1564"]},"publication_status":"published","file":[{"checksum":"382eb67e62a77052a23887332d363f96","file_id":"7193","content_type":"application/pdf","access_level":"open_access","relation":"main_file","date_created":"2019-12-18T07:13:14Z","file_name":"2019_PhysRevResearch_Huber.pdf","date_updated":"2020-07-14T12:47:52Z","file_size":1370022,"creator":"dernst"}],"language":[{"iso":"eng"}],"project":[{"_id":"260C2330-B435-11E9-9278-68D0E5697425","call_identifier":"H2020","grant_number":"754411","name":"ISTplus - Postdoctoral Fellowships"}],"article_number":"033177","author":[{"full_name":"Huber, D.","last_name":"Huber","first_name":"D."},{"first_name":"H.-W.","full_name":"Hammer, H.-W.","last_name":"Hammer"},{"id":"37D278BC-F248-11E8-B48F-1D18A9856A87","first_name":"Artem","orcid":"0000-0003-0393-5525","full_name":"Volosniev, Artem","last_name":"Volosniev"}],"external_id":{"arxiv":["1908.02483"]},"article_processing_charge":"No","title":"In-medium bound states of two bosonic impurities in a one-dimensional Fermi gas","citation":{"mla":"Huber, D., et al. “In-Medium Bound States of Two Bosonic Impurities in a One-Dimensional Fermi Gas.” Physical Review Research, vol. 1, no. 3, 033177, American Physical Society, 2019, doi:10.1103/physrevresearch.1.033177.","short":"D.

At the microscopic level, this effect governs the transfer between electron spin and orbital angular momentum, and lattice degrees of freedom, understanding which is key for molecular magnets, nano-magneto-mechanics, spintronics, and ultrafast magnetism. Until now, the timescales of electron-to-lattice angular momentum transfer remain unclear, since modeling this process on a microscopic level requires the addition of an infinite amount of quantum angular momenta. We show that this problem can be solved by reformulating it in terms of the recently discovered angulon quasiparticles, which results in a rotationally invariant quantum many-body theory. In particular, we demonstrate that nonperturbative effects take place even if the electron-phonon coupling is weak and give rise to angular momentum transfer on femtosecond timescales.","lang":"eng"}],"issue":"6","volume":99,"language":[{"iso":"eng"}],"publication_status":"published","project":[{"_id":"26031614-B435-11E9-9278-68D0E5697425","call_identifier":"FWF","grant_number":"P29902","name":"Quantum rotations in the presence of a many-body environment"}],"article_number":"064428","title":"Quantum many-body dynamics of the Einstein-de Haas effect","author":[{"first_name":"Johann H","last_name":"Mentink","full_name":"Mentink, Johann H"},{"full_name":"Katsnelson, Mikhail","last_name":"Katsnelson","first_name":"Mikhail"},{"orcid":"0000-0002-6990-7802","full_name":"Lemeshko, Mikhail","last_name":"Lemeshko","id":"37CB05FA-F248-11E8-B48F-1D18A9856A87","first_name":"Mikhail"}],"article_processing_charge":"No","external_id":{"isi":["000459223400004"],"arxiv":["1802.01638"]},"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","citation":{"mla":"Mentink, Johann H., et al. “Quantum Many-Body Dynamics of the Einstein-de Haas Effect.” Physical Review B, vol. 99, no. 6, 064428, American Physical Society, 2019, doi:10.1103/PhysRevB.99.064428.","short":"J.H.

Unlike Coulomb or contactlike interactions found in many atomic, molecular, and condensed-matter systems, this interaction is long-ranged and highly anisotropic, as it changes from repulsive to attractive depending on the relative positions and orientation of the dipoles. Because of this unique property, many exotic, symmetry-breaking collective states have been recently predicted for cold dipolar gases, but only a few have been experimentally detected and only in dilute atomic dipolar Bose-Einstein condensates. Here, we report on the first observation of attractive dipolar coupling between excitonic dipoles using a new design of stacked semiconductor bilayers. We show that the presence of a dipolar exciton fluid in one bilayer modifies the spatial distribution and increases the binding energy of excitonic dipoles in a vertically remote layer. The binding energy changes are explained using a many-body polaron model describing the deformation of the exciton cloud due to its interaction with a remote dipolar exciton. The surprising nonmonotonic dependence on the cloud density indicates the important role of dipolar correlations, which is unique to dense, strongly interacting dipolar solid-state systems. Our concept provides a route for the realization of dipolar lattices with strong anisotropic interactions in semiconductor systems, which open the way for the observation of theoretically predicted new and exotic collective phases, as well as for engineering and sensing their collective excitations."}],"oa_version":"Published Version","file_date_updated":"2020-07-14T12:47:40Z","department":[{"_id":"MiLe"}],"date_updated":"2024-02-28T13:12:48Z","ddc":["530"],"type":"journal_article","article_type":"original","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)"},"status":"public","_id":"6786","doi":"10.1103/PhysRevX.9.021026","date_published":"2019-05-08T00:00:00Z","date_created":"2019-08-11T21:59:20Z","isi":1,"has_accepted_license":"1","year":"2019","day":"08","publication":"Physical Review X","quality_controlled":"1","publisher":"American Physical Society","oa":1,"author":[{"first_name":"Colin","full_name":"Hubert, Colin","last_name":"Hubert"},{"full_name":"Baruchi, Yifat","last_name":"Baruchi","first_name":"Yifat"},{"first_name":"Yotam","last_name":"Mazuz-Harpaz","full_name":"Mazuz-Harpaz, Yotam"},{"first_name":"Kobi","full_name":"Cohen, Kobi","last_name":"Cohen"},{"full_name":"Biermann, Klaus","last_name":"Biermann","first_name":"Klaus"},{"first_name":"Mikhail","id":"37CB05FA-F248-11E8-B48F-1D18A9856A87","last_name":"Lemeshko","orcid":"0000-0002-6990-7802","full_name":"Lemeshko, Mikhail"},{"first_name":"Ken","full_name":"West, Ken","last_name":"West"},{"full_name":"Pfeiffer, Loren","last_name":"Pfeiffer","first_name":"Loren"},{"full_name":"Rapaport, Ronen","last_name":"Rapaport","first_name":"Ronen"},{"last_name":"Santos","full_name":"Santos, Paulo","first_name":"Paulo"}],"external_id":{"isi":["000467402900001"],"arxiv":["1807.11238"]},"article_processing_charge":"No","title":"Attractive dipolar coupling between stacked exciton fluids","citation":{"ama":"Hubert C, Baruchi Y, Mazuz-Harpaz Y, et al.

We show that this behavior leads to a modification of the usual Berezinskii-Kosterlitz-Thouless (BKT) transition in two dimensions. We extend the renormalization of the superfluid densities at finite temperature using the renormalization-group approach and find that the vortices of one component have a large influence on the superfluid properties of the other, mediated by the nondissipative drag.

Molecular angular momentum is naturally quantized, time evolution is governed by a well-known Hamiltonian with only a few accurately known parameters, and transitions between rotational levels can be driven by external fields from various parts of the electromagnetic spectrum. Control over the rotational motion can be exerted in one-, two-, and many-body scenarios, thereby allowing one to probe Anderson localization, target stereoselectivity of bimolecular reactions, or encode quantum information to name just a few examples. The corresponding approaches to quantum control are pursued within separate, and typically disjoint, subfields of physics, including ultrafast science, cold collisions, ultracold gases, quantum information science, and condensed-matter physics. It is the purpose of this review to present the various control phenomena, which all rely on the same underlying physics, within a unified framework. To this end, recall the Hamiltonian for free rotations, assuming the rigid rotor approximation to be valid, and summarize the different ways for a rotor to interact with external electromagnetic fields. These interactions can be exploited for control—from achieving alignment, orientation, or laser cooling in a one-body framework, steering bimolecular collisions, or realizing a quantum computer or quantum simulator in the many-body setting.","lang":"eng"}],"month":"09","intvolume":" 91","scopus_import":"1","main_file_link":[{"url":"https://arxiv.org/abs/1810.11338","open_access":"1"}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","citation":{"chicago":"Koch, Christiane P., Mikhail Lemeshko, and Dominique Sugny. “Quantum Control of Molecular Rotation.” Reviews of Modern Physics.

In this work, we focus on hyperfine states of lithiumlike heavy-Z isotopes and quantify how much quantum interference changes the observed transition frequencies. The process of photon excitation and subsequent photon decay for the transition 2s→2p→2s is implemented with fully relativistic and full-multipole frameworks, which are relevant for such relativistic atomic systems. We consider the isotopes Pb79+207 and Bi80+209 due to experimental interest, as well as other examples of isotopes with lower Z, namely Pr56+141 and Ho64+165. We conclude that quantum interference can induce shifts up to 11% of the linewidth in the measurable resonances of the considered isotopes, if interference between resonances is neglected. The inclusion of relativity decreases the cross section by 35%, mainly due to the complete retardation form of the electric dipole multipole. However, the contribution of the next higher multipoles (e.g., magnetic quadrupole) to the cross section is negligible. This makes the contribution of relativity and higher-order multipoles to the quantum interference induced shifts a minor effect, even for heavy-Z elements."}],"department":[{"_id":"MiLe"}],"date_updated":"2023-09-15T12:09:35Z","status":"public","article_type":"original","type":"journal_article","_id":"427"},{"article_number":"255302","project":[{"grant_number":"291734","name":"International IST Postdoc Fellowship Programme","_id":"25681D80-B435-11E9-9278-68D0E5697425","call_identifier":"FP7"},{"call_identifier":"FWF","_id":"26031614-B435-11E9-9278-68D0E5697425","grant_number":"P29902","name":"Quantum rotations in the presence of a many-body environment"}],"citation":{"mla":"Yakaboylu, Enderalp, et al. “Quantum Groups as Hidden Symmetries of Quantum Impurities.” Physical Review Letters, vol. 121, no. 25, 255302, American Physical Society, 2018, doi:10.1103/PhysRevLett.121.255302.","ama":"Yakaboylu E, Shkolnikov M, Lemeshko M.

In particular, we show that, if the symmetry of a free quantum particle corresponds to a Lie group G, in the presence of a many-body environment this particle can be described by a deformed group, Gq. Crucially, the single deformation parameter, q, contains all the information about the many-particle interactions in the system. We exemplify our approach by considering a quantum rotor interacting with a bath of bosons, and demonstrate that extracting the value of q from closed-form solutions in the perturbative regime allows one to predict the behavior of the system for arbitrary values of the impurity-bath coupling strength, in good agreement with nonperturbative calculations. Furthermore, the value of the deformation parameter allows one to predict at which coupling strengths rotor-bath interactions result in a formation of a stable quasiparticle. The approach based on quantum groups does not only allow for a drastic simplification of impurity problems, but also provides valuable insights into hidden symmetries of interacting many-particle systems."}],"oa_version":"Preprint","main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/1809.00222"}],"scopus_import":"1","intvolume":" 121","month":"12","publication_status":"published","publication_identifier":{"issn":["00319007"]},"language":[{"iso":"eng"}],"ec_funded":1,"volume":121,"issue":"25"},{"month":"07","intvolume":" 32","scopus_import":"1","main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/1710.11171"}],"oa_version":"Preprint","abstract":[{"text":"We analyze the theoretical derivation of the beyond-mean-field equation of state for two-dimensional gas of dilute, ultracold alkali-metal atoms in the Bardeen–Cooper–Schrieffer (BCS) to Bose–Einstein condensate (BEC) crossover. We show that at zero temperature our theory — considering Gaussian fluctuations on top of the mean-field equation of state — is in very good agreement with experimental data. Subsequently, we investigate the superfluid density at finite temperature and its renormalization due to the proliferation of vortex–antivortex pairs. By doing so, we determine the Berezinskii–Kosterlitz–Thouless (BKT) critical temperature — at which the renormalized superfluid density jumps to zero — as a function of the inter-atomic potential strength. We find that the Nelson–Kosterlitz criterion overestimates the BKT temperature with respect to the renormalization group equations, this effect being particularly relevant in the intermediate regime of the crossover.","lang":"eng"}],"issue":"17","volume":32,"language":[{"iso":"eng"}],"publication_status":"published","status":"public","type":"journal_article","_id":"420","department":[{"_id":"MiLe"}],"date_updated":"2023-09-18T08:09:59Z","quality_controlled":"1","publisher":"World Scientific Publishing","oa":1,"date_published":"2018-07-10T00:00:00Z","doi":"10.1142/S0217979218400222","date_created":"2018-12-11T11:46:22Z","page":"1840022","day":"10","publication":"International Journal of Modern Physics B","isi":1,"year":"2018","title":"Renormalization of the superfluid density in the two-dimensional BCS-BEC crossover","publist_id":"7402","author":[{"orcid":"0000-0001-8823-9777","full_name":"Bighin, Giacomo","last_name":"Bighin","first_name":"Giacomo","id":"4CA96FD4-F248-11E8-B48F-1D18A9856A87"},{"last_name":"Salasnich","full_name":"Salasnich, Luca","first_name":"Luca"}],"article_processing_charge":"No","external_id":{"isi":["000438217300007"]},"user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","citation":{"short":"G.

Throughout the article, Rayleigh and Raman scattering are taken as examples of two-photon processes. The present method provides a clear distinction between the Thomson scattering, regarded as classical scattering, and quantum contributions. Such a distinction lets us derive general results concerning light scattering.

In particular, we demonstrate a possibility to control resonant emission of phonons with a given angular momentum using a magnetic field.","lang":"eng"}],"oa_version":"Preprint","scopus_import":"1","main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/1711.09904"}],"month":"03","intvolume":" 148","publication_status":"published","language":[{"iso":"eng"}],"volume":148,"related_material":{"record":[{"status":"public","id":"10759","relation":"dissertation_contains"}]},"issue":"10","ec_funded":1},{"date_created":"2019-04-17T10:53:38Z","date_published":"2018-10-16T00:00:00Z","doi":"10.1103/physrevlett.121.165301","year":"2018","isi":1,"publication":"Physical Review Letters","day":"16","oa":1,"publisher":"American Physical Society","quality_controlled":"1","article_processing_charge":"No","external_id":{"isi":["000447468400008"],"arxiv":["1803.07990"]},"author":[{"first_name":"Giacomo","id":"4CA96FD4-F248-11E8-B48F-1D18A9856A87","full_name":"Bighin, Giacomo","orcid":"0000-0001-8823-9777","last_name":"Bighin"},{"first_name":"Timur","last_name":"Tscherbul","full_name":"Tscherbul, Timur"},{"id":"37CB05FA-F248-11E8-B48F-1D18A9856A87","first_name":"Mikhail","full_name":"Lemeshko, Mikhail","orcid":"0000-0002-6990-7802","last_name":"Lemeshko"}],"title":"Diagrammatic Monte Carlo approach to angular momentum in quantum many-particle systems","citation":{"mla":"Bighin, Giacomo, et al. “Diagrammatic Monte Carlo Approach to Angular Momentum in Quantum Many-Particle Systems.” Physical Review Letters, vol. 121, no. 16, 165301, American Physical Society, 2018, doi:10.1103/physrevlett.121.165301.","ieee":"G.

Owing to advances in laser technology, electric fields comparable to those electrons experience in atoms are readily generated and open opportunities to dynamically investigate the process of electron tunneling through the potential barrier formed by the superposition of both laser and atomic fields. Attosecond-time and angstrom-space resolution of the strong laser-field technique allow to address fundamental questions related to tunneling, which are still open and debated: Which time is spent under the barrier and what momentum is picked up by the particle in the meantime? In this combined experimental and theoretical study we demonstrate that for strong-field ionization the leading quantum mechanical Wigner treatment for the time resolved description of tunneling is valid. We achieve a high sensitivity on the tunneling barrier and unambiguously isolate its effects by performing a differential study of two systems with almost identical tunneling geometry. Moreover, working with a low frequency laser, we essentially limit the non-adiabaticity of the process as a major source of uncertainty. The agreement between experiment and theory implies two substantial corrections with respect to the widely employed quasiclassical treatment: In addition to a non-vanishing longitudinal momentum along the laser field-direction we provide clear evidence for a non-zero tunneling time delay. This addresses also the fundamental question how the transition occurs from the tunnel barrier to free space classical evolution of the ejected electron.","lang":"eng"}],"intvolume":" 999","month":"07","alternative_title":["Journal of Physics: Conference Series"],"scopus_import":1,"language":[{"iso":"eng"}],"file":[{"checksum":"6e70b525a84f6d5fb175c48e9f5cb59a","file_id":"5871","access_level":"open_access","relation":"main_file","content_type":"application/pdf","date_created":"2019-01-22T08:34:10Z","file_name":"2017_Physics_Camus.pdf","creator":"dernst","date_updated":"2020-07-14T12:46:00Z","file_size":949321}],"publication_status":"published","publication_identifier":{"issn":["17426588"]},"volume":999,"related_material":{"record":[{"status":"public","id":"6013","relation":"later_version"}]},"issue":"1"},{"issue":"2","volume":119,"related_material":{"record":[{"status":"public","id":"313","relation":"earlier_version"}]},"publication_status":"published","publication_identifier":{"issn":["0031-9007"],"eissn":["1079-7114"]},"language":[{"iso":"eng"}],"main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/1611.03701"}],"scopus_import":1,"intvolume":" 119","month":"07","abstract":[{"text":"The first hundred attoseconds of the electron dynamics during strong field tunneling ionization are investigated.

One of the pivotal challenges in this field is the designation of a consistent interpretation framework within which we can describe quantitatively the universal features of those systems. Here we analyze in a detailed manner the principal experimental data and compare them quantitatively with the approach based on a single-band model of strongly correlated electrons supplemented with strong antiferromagnetic (super)exchange interaction (the so-called t−J−U model). The model rationale is provided by estimating its microscopic parameters on the basis of the three-band approach for the Cu-O plane. We use our original full Gutzwiller wave-function solution by going beyond the renormalized mean-field theory (RMFT) in a systematic manner. Our approach reproduces very well the observed hole doping (δ) dependence of the kinetic-energy gain in the superconducting phase, one of the principal non-Bardeen-Cooper-Schrieffer features of the cuprates. The calculated Fermi velocity in the nodal direction is practically δ-independent and its universal value agrees very well with that determined experimentally. Also, a weak doping dependence of the Fermi wave vector leads to an almost constant value of the effective mass in a pure superconducting phase which is both observed in experiment and reproduced within our approach. An assessment of the currently used models (t−J, Hubbard) is carried out and the results of the canonical RMFT as a zeroth-order solution are provided for comparison to illustrate the necessity of the introduced higher-order contributions."}],"oa_version":"Submitted Version","article_processing_charge":"No","external_id":{"isi":["000391852800006"]},"author":[{"full_name":"Spałek, Jozef","last_name":"Spałek","first_name":"Jozef"},{"first_name":"Michał","full_name":"Zegrodnik, Michał","last_name":"Zegrodnik"},{"first_name":"Jan","id":"46C405DE-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-1629-3675","full_name":"Kaczmarczyk, Jan","last_name":"Kaczmarczyk"}],"publist_id":"6195","title":"Universal properties of high temperature superconductors from real space pairing t-J-U model and its quantitative comparison with experiment","citation":{"ieee":"J.
