[{"abstract":[{"text":"We study a linear rotor in a bosonic bath within the angulon formalism. Our focus is on systems where isotropic or anisotropic impurity-boson interactions support a shallow bound state. To study the fate of the angulon in the vicinity of bound-state formation, we formulate a beyond-linear-coupling angulon Hamiltonian. First, we use it to study attractive, spherically symmetric impurity-boson interactions for which the linear rotor can be mapped onto a static impurity. The well-known polaron formalism provides an adequate description in this limit. Second, we consider anisotropic potentials, and show that the presence of a shallow bound state with pronounced anisotropic character leads to a many-body instability that washes out the angulon dynamics.","lang":"eng"}],"oa_version":"None","scopus_import":"1","intvolume":" 109","month":"01","publication_status":"published","publication_identifier":{"issn":["2469-9950"],"eissn":["2469-9969"]},"language":[{"iso":"eng"}],"ec_funded":1,"issue":"1","volume":109,"_id":"14845","type":"journal_article","article_type":"original","status":"public","date_updated":"2024-01-23T10:51:09Z","department":[{"_id":"MiLe"}],"acknowledgement":"We would like to thank G.

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."}],"month":"02","intvolume":" 109","scopus_import":"1","main_file_link":[{"open_access":"1","url":"https://doi.org/10.48550/arXiv.2307.07256"}],"date_updated":"2024-02-26T09:45:20Z","department":[{"_id":"MiLe"}],"_id":"15004","status":"public","article_type":"original","type":"journal_article","day":"01","publication":"Physical Review A","year":"2024","doi":"10.1103/PhysRevA.109.023101","date_published":"2024-02-01T00:00:00Z","date_created":"2024-02-18T23:01:01Z","acknowledgement":"We thank Bretislav Friedrich, Marjan Mirahmadi, Artem Volosniev, and Burkhard Schmidt for insightful discussions.

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."}],"intvolume":" 6","month":"02","scopus_import":"1","language":[{"iso":"eng"}],"file":[{"file_name":"2024_PhysicalReviewResearch_Jin.pdf","date_created":"2024-03-04T07:53:08Z","creator":"dernst","file_size":4025988,"date_updated":"2024-03-04T07:53:08Z","success":1,"checksum":"ba2ae3e3a011f8897d3803c9366a67e2","file_id":"15054","relation":"main_file","access_level":"open_access","content_type":"application/pdf"}],"publication_status":"published","publication_identifier":{"issn":["2643-1564"]},"issue":"1","volume":6,"article_number":"013158","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","citation":{"ieee":"S.

Increasing repulsion leads to the appearance of nonadiabatic couplings between the fast bath and slow impurity degrees of freedom, which reduce the parity symmetry of the latter according to the pseudo Jahn-Teller effect. The presence of this mechanism is associated to a conical intersection involving the impurity position and the inverse of the interaction strength, which acts as a synthetic dimension. We elucidate the presence of these effects via a detailed ground-state analysis involving the comparison of ab initio fully correlated simulations with effective models.

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"}],"intvolume":" 5","month":"01","scopus_import":"1","language":[{"iso":"eng"}],"file":[{"file_id":"12546","checksum":"6068b62874c0099628a108bb9c5c6bd2","success":1,"access_level":"open_access","relation":"main_file","content_type":"application/pdf","date_created":"2023-02-13T10:38:10Z","file_name":"2023_PhysicalReviewResearch_Ghazaryan.pdf","creator":"dernst","date_updated":"2023-02-13T10:38:10Z","file_size":865150}],"publication_status":"published","publication_identifier":{"issn":["2643-1564"]},"ec_funded":1,"issue":"1","volume":5,"_id":"12534","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)"},"type":"journal_article","article_type":"original","ddc":["530"],"date_updated":"2023-02-20T07:02:00Z","file_date_updated":"2023-02-13T10:38:10Z","department":[{"_id":"MiLe"}],"acknowledgement":"We thank Rafael Barfknecht for help at the initial stages of this project; Fabian Brauneis for useful discussions; Miguel A.

Understanding the interplay between these two subsystems is a challenging problem, but it is this coupling that is widely conjectured to be responsible for the unique behavior of photocarriers in these materials. 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. Our results pave the way for understanding electric fields in lead-halide perovskites using infrared bond spectroscopy."}],"month":"07","intvolume":" 14","ddc":["530"],"date_updated":"2023-07-19T06:59:19Z","file_date_updated":"2023-07-19T06:55:39Z","department":[{"_id":"MiLe"},{"_id":"ZhAl"}],"_id":"13251","status":"public","keyword":["General Materials Science","Physical and Theoretical Chemistry"],"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)"},"day":"05","publication":"The Journal of Physical Chemistry Letters","has_accepted_license":"1","isi":1,"year":"2023","doi":"10.1021/acs.jpclett.3c01158","date_published":"2023-07-05T00:00:00Z","date_created":"2023-07-18T11:13:17Z","page":"6309-6314","acknowledgement":"We thank Bingqing Cheng and Hong-Zhou Ye for valuable discussions; Y.W.’s work at IST Austria was supported through ISTernship summer internship program funded by OeADGmbH; D.L. and Z.A. acknowledge support by IST Austria (ISTA); M.L. acknowledges support by the European Research Council (ERC) Starting Grant No. 801770 (ANGULON).\r\nA.A.Z. and O.M.B. acknowledge support by KAUST.","publisher":"American Chemical Society","quality_controlled":"1","oa":1,"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","citation":{"ista":"Wei Y, Volosniev A, Lorenc D, Zhumekenov AA, Bakr OM, Lemeshko M, Alpichshev Z. 2023.

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.","lang":"eng"}],"oa_version":"Preprint","main_file_link":[{"open_access":"1","url":"https://doi.org/10.48550/arXiv.2203.09443"}],"scopus_import":"1","intvolume":" 130","month":"03","citation":{"mla":"Volosniev, Artem, et al. “Spin-Electric Coupling in Lead Halide Perovskites.” Physical Review Letters, vol. 130, no. 10, 106901, American Physical Society, 2023, doi:10.1103/physrevlett.130.106901.","apa":"Volosniev, A., Shiva Kumar, A., Lorenc, D., Ashourishokri, Y., Zhumekenov, A.

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."}],"month":"03","intvolume":" 130","scopus_import":"1","main_file_link":[{"url":"https://doi.org/10.48550/arXiv.2206.07067","open_access":"1"}]},{"oa":1,"quality_controlled":"1","publisher":"American Physical Society","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.","date_created":"2023-04-02T22:01:10Z","date_published":"2023-03-01T00:00:00Z","doi":"10.1103/PhysRevB.107.104502","year":"2023","isi":1,"publication":"Physical Review B","day":"01","article_number":"104502","article_processing_charge":"No","external_id":{"isi":["000945526400003"],"arxiv":["2211.02492"]},"author":[{"id":"4AF46FD6-F248-11E8-B48F-1D18A9856A87","first_name":"Areg","last_name":"Ghazaryan","orcid":"0000-0001-9666-3543","full_name":"Ghazaryan, Areg"},{"last_name":"Holder","full_name":"Holder, Tobias","first_name":"Tobias"},{"last_name":"Berg","full_name":"Berg, Erez","first_name":"Erez"},{"id":"47809E7E-F248-11E8-B48F-1D18A9856A87","first_name":"Maksym","last_name":"Serbyn","full_name":"Serbyn, Maksym","orcid":"0000-0002-2399-5827"}],"title":"Multilayer graphenes as a platform for interaction-driven physics and topological superconductivity","citation":{"mla":"Ghazaryan, Areg, et al. “Multilayer Graphenes as a Platform for Interaction-Driven Physics and Topological Superconductivity.” Physical Review B, vol. 107, no. 10, 104502, American Physical Society, 2023, doi:10.1103/PhysRevB.107.104502.","short":"A.

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."}],"oa_version":"Preprint","related_material":{"link":[{"relation":"press_release","url":"https://ista.ac.at/en/news/reaching-superconductivity-layer-by-layer/","description":"News on the ISTA website"}]},"volume":107,"issue":"10","publication_status":"published","publication_identifier":{"issn":["2469-9950"],"eissn":["2469-9969"]},"language":[{"iso":"eng"}],"article_type":"original","type":"journal_article","status":"public","_id":"12790","department":[{"_id":"MaSe"},{"_id":"MiLe"}],"date_updated":"2023-08-01T13:59:29Z"},{"_id":"12831","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)"},"type":"journal_article","article_type":"original","ddc":["530"],"date_updated":"2023-08-01T14:08:47Z","file_date_updated":"2023-04-17T07:28:38Z","department":[{"_id":"MiLe"}],"oa_version":"Published Version","abstract":[{"lang":"eng","text":"The angulon, a quasiparticle formed by a quantum rotor dressed by the excitations of a many-body bath, can be used to describe an impurity rotating in a fluid or solid environment. 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."}],"intvolume":" 158","month":"04","scopus_import":"1","language":[{"iso":"eng"}],"file":[{"content_type":"application/pdf","access_level":"open_access","relation":"main_file","file_id":"12841","checksum":"8d801babea4df48e08895c76571bb19e","success":1,"date_updated":"2023-04-17T07:28:38Z","file_size":7388057,"creator":"dernst","date_created":"2023-04-17T07:28:38Z","file_name":"2023_JourChemicalPhysics_Zeng.pdf"}],"publication_status":"published","publication_identifier":{"eissn":["1089-7690"]},"ec_funded":1,"issue":"13","volume":158,"article_number":"134301","project":[{"grant_number":"801770","name":"Angulon: physics and applications of a new quasiparticle","call_identifier":"H2020","_id":"2688CF98-B435-11E9-9278-68D0E5697425"}],"user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","citation":{"mla":"Zeng, Zhongda, et al. “Variational Theory of Angulons and Their Rotational Spectroscopy.” The Journal of Chemical Physics, vol. 158, no. 13, 134301, American Institute of Physics, 2023, doi:10.1063/5.0135893.","short":"Z.

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","main_file_link":[{"open_access":"1","url":"https://doi.org/10.48550/arXiv.2207.13130"}],"scopus_import":"1","intvolume":" 107","month":"04","publication_status":"published","publication_identifier":{"eissn":["2469-9934"],"issn":["2469-9926"]},"language":[{"iso":"eng"}],"ec_funded":1,"issue":"4","volume":107,"article_number":"042216","project":[{"grant_number":"754411","name":"ISTplus - Postdoctoral Fellowships","_id":"260C2330-B435-11E9-9278-68D0E5697425","call_identifier":"H2020"}],"citation":{"ista":"Suzuki F, Unruh WG. 2023.

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.
