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."}],"file":[{"file_name":"2023_CommPhysics_Brauneis.pdf","date_created":"2023-09-05T08:45:49Z","relation":"main_file","content_type":"application/pdf","date_updated":"2023-09-05T08:45:49Z","success":1,"creator":"dernst","file_size":855960,"checksum":"6edfc59b0ee7dc406d0968b05236e83d","access_level":"open_access","file_id":"14268"}],"publication_status":"published","arxiv":1,"keyword":["General Physics and Astronomy"],"day":"22","volume":6,"type":"journal_article","article_processing_charge":"Yes (via OA deal)","publisher":"Springer Nature","publication":"Communications Physics"},{"author":[{"last_name":"Henderson","id":"13C09E74-18D9-11E9-8878-32CFE5697425","full_name":"Henderson, Paul M","first_name":"Paul M","orcid":"0000-0002-5198-7445"},{"full_name":"Ghazaryan, Areg","id":"4AF46FD6-F248-11E8-B48F-1D18A9856A87","last_name":"Ghazaryan","orcid":"0000-0001-9666-3543","first_name":"Areg"},{"first_name":"Alexander A.","last_name":"Zibrov","full_name":"Zibrov, Alexander A."},{"first_name":"Andrea F.","last_name":"Young","full_name":"Young, Andrea F."},{"first_name":"Maksym","orcid":"0000-0002-2399-5827","full_name":"Serbyn, Maksym","last_name":"Serbyn","id":"47809E7E-F248-11E8-B48F-1D18A9856A87"}],"date_published":"2023-09-15T00:00:00Z","date_updated":"2023-09-20T09:38:24Z","external_id":{"arxiv":["2210.06310"]},"language":[{"iso":"eng"}],"oa_version":"Preprint","scopus_import":"1","month":"09","doi":"10.1103/physrevb.108.125411","acknowledgement":"A.F.Y. acknowledges primary support from the Department of Energy under award DE-SC0020043, and additional support from the Gordon and Betty Moore Foundation under award GBMF9471 for group operations.","publication_identifier":{"eissn":["2469-9969"],"issn":["2469-9950"]},"article_number":"125411","department":[{"_id":"MaSe"},{"_id":"ChLa"},{"_id":"MiLe"}],"publication_status":"published","arxiv":1,"main_file_link":[{"open_access":"1","url":"https://doi.org/10.48550/arXiv.2210.06310"}],"_id":"14320","intvolume":"       108","abstract":[{"lang":"eng","text":"The development of two-dimensional materials has resulted in a diverse range of novel, high-quality compounds with increasing complexity. 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."}],"status":"public","article_processing_charge":"No","issue":"12","publication":"Physical Review B","publisher":"American Physical Society","volume":108,"day":"15","type":"journal_article","quality_controlled":"1","article_type":"original","date_created":"2023-09-12T07:12:12Z","year":"2023","citation":{"short":"P.M.

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."}],"intvolume":"      1042","publication_status":"published","arxiv":1,"department":[{"_id":"MiLe"}],"isi":1,"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.

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.

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"}],"pmid":1,"article_processing_charge":"No","publisher":"American Physical Society","publication":"Physical Review Letters","issue":"10","day":"10","keyword":["General Physics and Astronomy"],"volume":130,"type":"journal_article","article_type":"original","quality_controlled":"1","corr_author":"1","year":"2023","date_created":"2023-03-14T13:11:59Z","citation":{"mla":"Volosniev, Artem, et al. “Spin-Electric Coupling in Lead Halide Perovskites.” <i>Physical Review Letters</i>, vol. 130, no. 10, 106901, American Physical Society, 2023, doi:<a href=\"https://doi.org/10.1103/physrevlett.130.106901\">10.1103/physrevlett.130.106901</a>.","ieee":"A.

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."}],"status":"public","publication_status":"published","arxiv":1,"volume":107,"day":"01","type":"journal_article","article_processing_charge":"No","publication":"Physical Review B","issue":"10","publisher":"American Physical Society","citation":{"ieee":"A.

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.

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.","lang":"eng"}],"publication_status":"published","arxiv":1,"isi":1,"department":[{"_id":"MiLe"}],"article_number":"2202631","acknowledgement":"The authors acknowledge insightful discussions with Prof. Wang Yao and graphics by Rezlind Bushati.

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."}],"intvolume":"       107","status":"public","main_file_link":[{"open_access":"1","url":"https://doi.org/10.48550/arXiv.2207.13130"}],"ec_funded":1,"title":"Numerical quantum clock simulations for measuring tunneling times","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","date_created":"2023-05-07T22:01:03Z","year":"2023","quality_controlled":"1","corr_author":"1","article_type":"original","oa":1,"citation":{"apa":"Suzuki, F., &#38; Unruh, W.

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.","lang":"eng"}],"intvolume":"        14","status":"public","publication_status":"published","file":[{"checksum":"c0c040063f06a51b9c463adc504f1a23","file_size":2121252,"file_id":"13253","access_level":"open_access","relation":"main_file","content_type":"application/pdf","file_name":"2023_JourPhysChemistry_Wei.pdf","date_created":"2023-07-19T06:55:39Z","creator":"dernst","success":1,"date_updated":"2023-07-19T06:55:39Z"}],"arxiv":1,"tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","short":"CC BY (4.0)","image":"/images/cc_by.png"},"department":[{"_id":"MiLe"},{"_id":"ZhAl"}],"isi":1,"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.","publication_identifier":{"eissn":["1948-7185"]},"doi":"10.1021/acs.jpclett.3c01158","scopus_import":"1","oa_version":"Published Version","has_accepted_license":"1","month":"07","external_id":{"pmid":["37405449"],"isi":["001022811500001"],"arxiv":["2304.14198"]},"language":[{"iso":"eng"}],"date_updated":"2025-04-23T13:01:50Z","project":[{"grant_number":"801770","_id":"2688CF98-B435-11E9-9278-68D0E5697425","call_identifier":"H2020","name":"Angulon: physics and applications of a new quasiparticle"}],"author":[{"first_name":"Yujing","orcid":"0000-0001-8913-9719","full_name":"Wei, Yujing","id":"0c5ff007-2600-11ee-b896-98bd8d663294","last_name":"Wei"},{"orcid":"0000-0003-0393-5525","first_name":"Artem","id":"37D278BC-F248-11E8-B48F-1D18A9856A87","last_name":"Volosniev","full_name":"Volosniev, Artem"},{"first_name":"Dusan","id":"40D8A3E6-F248-11E8-B48F-1D18A9856A87","full_name":"Lorenc, Dusan","last_name":"Lorenc"},{"full_name":"Zhumekenov, Ayan A.","last_name":"Zhumekenov","first_name":"Ayan A."},{"full_name":"Bakr, Osman M.","last_name":"Bakr","first_name":"Osman M."},{"orcid":"0000-0002-6990-7802","first_name":"Mikhail","last_name":"Lemeshko","full_name":"Lemeshko, Mikhail","id":"37CB05FA-F248-11E8-B48F-1D18A9856A87"},{"first_name":"Zhanybek","orcid":"0000-0002-7183-5203","full_name":"Alpichshev, Zhanybek","id":"45E67A2A-F248-11E8-B48F-1D18A9856A87","last_name":"Alpichshev"}],"date_published":"2023-07-05T00:00:00Z","ddc":["530"]},{"oa":1,"citation":{"ista":"Rammelmüller L, Huber D, Volosniev A. 2023.

The model represents a few-body analogue of a magnetic impurity in the vicinity of an s-wave superconductor. Already for a few particles we find a ground-state level crossing between sectors with different fermion parities. We interpret this crossing as a few-body precursor of a quantum phase transition, which occurs when the impurity \"breaks\" a Cooper pair. This picture is further corroborated by analyzing density-density correlations in momentum space. Finally, we discuss how the system may be realized with existing cold-atoms platforms.","lang":"eng"}],"arxiv":1,"file":[{"access_level":"open_access","file_id":"13328","checksum":"ffdb70b9ae7aa45ea4ea6096ecbd6431","file_size":1163444,"date_updated":"2023-07-31T08:44:38Z","success":1,"creator":"dernst","file_name":"2023_SciPostPhysics_Rammelmueller.pdf","date_created":"2023-07-31T08:44:38Z","relation":"main_file","content_type":"application/pdf"}],"publication_status":"published","isi":1,"tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","short":"CC BY (4.0)","image":"/images/cc_by.png"},"department":[{"_id":"MiLe"}],"article_number":"006","publication_identifier":{"issn":["2542-4653"]},"doi":"10.21468/scipostphys.14.1.006","month":"01","has_accepted_license":"1","scopus_import":"1","oa_version":"Published Version","language":[{"iso":"eng"}],"external_id":{"arxiv":["2204.01606"],"isi":["001000325800008"]},"date_updated":"2023-12-13T11:39:32Z","ddc":["530"],"date_published":"2023-01-24T00:00:00Z","author":[{"last_name":"Rammelmüller","full_name":"Rammelmüller, Lukas","first_name":"Lukas"},{"last_name":"Huber","full_name":"Huber, David","first_name":"David"},{"last_name":"Čufar","full_name":"Čufar, Matija","first_name":"Matija"},{"first_name":"Joachim","last_name":"Brand","full_name":"Brand, Joachim"},{"full_name":"Hammer, Hans-Werner","last_name":"Hammer","first_name":"Hans-Werner"},{"id":"37D278BC-F248-11E8-B48F-1D18A9856A87","full_name":"Volosniev, Artem","last_name":"Volosniev","orcid":"0000-0003-0393-5525","first_name":"Artem"}]},{"type":"journal_article","page":"467-532","day":"16","keyword":["Geometry and Topology","Mathematical Physics"],"volume":14,"publisher":"European Mathematical Society","publication":"Quantum Topology","issue":"3","article_processing_charge":"Yes","status":"public","abstract":[{"text":"We prove the r-spin cobordism hypothesis in the setting of (weak) 2-categories for every positive integer r: the 2-groupoid of 2-dimensional fully extended r-spin TQFTs with given target is equivalent to the homotopy fixed points of an induced Spin 2r -action.

For r=1, we recover the oriented case (on which our proof builds), while ordinary spin structures correspond to r=2.\r\nTo construct examples, we explicitly describe Spin 2r​-homotopy fixed points in the equivariant completion of any symmetric monoidal 2-category.
