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. These results can be directly compared with future experiments."}],"oa_version":"Published Version","scopus_import":"1","intvolume":" 7","month":"09","date_updated":"2023-08-04T09:23:43Z","ddc":["530"],"file_date_updated":"2023-01-27T07:59:27Z","department":[{"_id":"MiLe"}],"_id":"12213","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":["Condensed Matter Physics","Electronic","Optical and Magnetic Materials"],"status":"public","year":"2022","isi":1,"has_accepted_license":"1","publication":"npj Quantum Materials","day":"10","date_created":"2023-01-16T09:46:01Z","date_published":"2022-09-10T00:00:00Z","doi":"10.1038/s41535-022-00496-w","acknowledgement":"E.M.P. thanks Eugenio Paris, Thorsten Schmitt, Krzysztof Wohlfeld, and other coauthors for an inspiring previous collaboration23, and is grateful to Gang Cao, Ambrose Seo, and Jungho Kim for insightful discussions.

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"}],"month":"10","intvolume":" 14","scopus_import":"1","file":[{"creator":"dernst","date_updated":"2023-01-24T10:56:12Z","file_size":843723,"date_created":"2023-01-24T10:56:12Z","file_name":"2022_Symmetry_Salsnich.pdf","access_level":"open_access","relation":"main_file","content_type":"application/pdf","file_id":"12361","checksum":"9b6bd0e484834dd76d7b26e3c5fba8bd","success":1}],"language":[{"iso":"eng"}],"publication_identifier":{"issn":["2073-8994"]},"publication_status":"published","issue":"10","volume":14,"_id":"12154","status":"public","keyword":["Physics and Astronomy (miscellaneous)","General Mathematics","Chemistry (miscellaneous)","Computer Science (miscellaneous)"],"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)"},"ddc":["530"],"date_updated":"2023-08-09T10:13:17Z","department":[{"_id":"MiLe"}],"file_date_updated":"2023-01-24T10:56:12Z","acknowledgement":"This research is partially supported by University of Padova, BIRD grant “Ultracold atoms\r\nin curved geometries”.

I apply analytic variational treatment to this Hamiltonian. Then, I introduce a variational approach for non-additive systems, based on artificial neural networks. 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.

Our main example is two-dimensional Yang–Mills theory with compact gauge group, which we treat in detail."}],"file_date_updated":"2021-02-03T15:00:30Z","department":[{"_id":"MiLe"}],"ddc":["510"],"date_updated":"2023-08-04T11:13:35Z","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":"8816"},{"doi":"10.1103/PhysRevLett.126.015301","date_published":"2021-01-08T00:00:00Z","date_created":"2021-01-17T23:01:10Z","day":"08","publication":"Physical Review Letters","isi":1,"year":"2021","quality_controlled":"1","publisher":"American Physical Society","oa":1,"acknowledgement":"We are grateful to A.

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.","lang":"eng"}],"department":[{"_id":"MiLe"},{"_id":"RoSe"}],"date_updated":"2023-08-07T13:32:10Z","status":"public","type":"journal_article","article_type":"original","_id":"9005"},{"project":[{"_id":"260C2330-B435-11E9-9278-68D0E5697425","call_identifier":"H2020","grant_number":"754411","name":"ISTplus - Postdoctoral Fellowships"}],"article_number":"025","title":"Shape of a sound wave in a weakly-perturbed Bose gas","article_processing_charge":"No","external_id":{"isi":["000646783100027"],"arxiv":["2004.08075"]},"author":[{"full_name":"Marchukov, Oleksandr","last_name":"Marchukov","first_name":"Oleksandr"},{"first_name":"Artem","id":"37D278BC-F248-11E8-B48F-1D18A9856A87","last_name":"Volosniev","orcid":"0000-0003-0393-5525","full_name":"Volosniev, Artem"}],"user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","citation":{"mla":"Marchukov, Oleksandr, and Artem Volosniev. “Shape of a Sound Wave in a Weakly-Perturbed Bose Gas.” SciPost Physics, vol. 10, no. 2, 025, SciPost Foundation, 2021, doi:10.21468/scipostphys.10.2.025.","ieee":"O.

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.","lang":"eng"}],"department":[{"_id":"MiLe"}],"date_updated":"2023-08-10T13:37:25Z","status":"public","type":"journal_article","article_type":"letter_note","_id":"9606"},{"publisher":"IOP Publishing","quality_controlled":"1","oa":1,"acknowledgement":"We thank Aidan Tracy for his input during the initial stages of this project.

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.

In this paper, we extend this approach to compute observables other than the energy. As an example, we calculate the densities, and phase fluctuations of one-dimensional Bose gases with one and two impurities. 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. The mean-field approximation reproduces the flow equation results for all values of the boson-impurity interaction strength as long as boson-boson interactions are weak."}],"title":"Impurities in a one-dimensional Bose gas: The flow equation approach","author":[{"full_name":"Brauneis, Fabian","last_name":"Brauneis","first_name":"Fabian"},{"first_name":"Hans-Werner","last_name":"Hammer","full_name":"Hammer, Hans-Werner"},{"last_name":"Lemeshko","full_name":"Lemeshko, Mikhail","orcid":"0000-0002-6990-7802","id":"37CB05FA-F248-11E8-B48F-1D18A9856A87","first_name":"Mikhail"},{"id":"37D278BC-F248-11E8-B48F-1D18A9856A87","first_name":"Artem","orcid":"0000-0003-0393-5525","full_name":"Volosniev, Artem","last_name":"Volosniev"}],"external_id":{"arxiv":["2101.10958"],"isi":["000680039500013"]},"article_processing_charge":"Yes","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","citation":{"chicago":"Brauneis, Fabian, Hans-Werner Hammer, Mikhail Lemeshko, and Artem Volosniev. “Impurities in a One-Dimensional Bose Gas: The Flow Equation Approach.” SciPost Physics.

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","month":"08","intvolume":" 127","date_updated":"2023-08-11T10:43:27Z","ddc":["539"],"file_date_updated":"2021-08-13T09:28:08Z","department":[{"_id":"MaSe"},{"_id":"GradSch"},{"_id":"MiLe"}],"_id":"9903","type":"journal_article","article_type":"letter_note","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":"2021","day":"06","publication":"Physical Review Letters","date_published":"2021-08-06T00:00:00Z","doi":"10.1103/physrevlett.127.060602","date_created":"2021-08-13T09:27:39Z","acknowledgement":"We acknowledge useful discussions with 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.","lang":"eng"}],"department":[{"_id":"MaSe"},{"_id":"MiLe"}],"date_updated":"2023-08-14T07:04:06Z","status":"public","keyword":["condensed matter - mesoscale and nanoscale physics","condensed matter - strongly correlated electrons","multidisciplinary"],"type":"journal_article","article_type":"original","_id":"10025","doi":"10.1038/s41586-021-03938-w","date_published":"2021-09-01T00:00:00Z","date_created":"2021-09-19T22:01:25Z","day":"01","publication":"Nature","isi":1,"year":"2021","publisher":"Springer Nature","quality_controlled":"1","oa":1,"acknowledgement":"The authors acknowledge discussions with A.

In this work, we propose a two-terminal cold-atom simulator to study that interaction. The proposed quantum simulator consists of strongly interacting atoms that occupy two temperature reservoirs connected by a one-dimensional link. First, we argue that the dynamics in the link can be described using an inhomogeneous Heisenberg spin chain whose couplings are defined by the local temperature. 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. A temperature gradient accelerates the impurity in one direction more than in the other, leading to an overall spin current similar to the spin Seebeck effect.","lang":"eng"}]},{"date_published":"2021-12-23T00:00:00Z","doi":"10.1088/1367-2630/ac4124","date_created":"2022-01-16T23:01:28Z","day":"23","publication":"New Journal of Physics","isi":1,"has_accepted_license":"1","year":"2021","publisher":"IOP Publishing","quality_controlled":"1","oa":1,"acknowledgement":"PG acknowledges support from National Science Foundation Awards No. DMR-1824265 for this work.

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.","lang":"eng"}],"department":[{"_id":"MiLe"}],"file_date_updated":"2022-01-17T10:01:58Z","ddc":["530"],"date_updated":"2023-08-17T06:54:54Z","status":"public","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":"10628"},{"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.

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.","lang":"eng"}],"acknowledged_ssus":[{"_id":"M-Shop"},{"_id":"NanoFab"}],"oa_version":"Preprint","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 illustrate that the coupling has a dramatic effect on localization properties, even with a small number of internal states participating in quantum dynamics.","lang":"eng"}],"intvolume":" 127","month":"10","main_file_link":[{"url":"https://arxiv.org/abs/2011.06279","open_access":"1"}],"scopus_import":"1","language":[{"iso":"eng"}],"publication_status":"published","publication_identifier":{"issn":["0031-9007"],"eissn":["1079-7114"]},"ec_funded":1,"volume":127,"issue":"16","_id":"10134","keyword":["General Physics and Astronomy"],"status":"public","article_type":"original","type":"journal_article","date_updated":"2024-02-29T12:34:10Z","department":[{"_id":"MiLe"}]}]
