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"}],"publication_status":"published","department":[{"_id":"MiLe"}],"volume":109,"quality_controlled":"1","publisher":"American Physical Society","date_published":"2024-01-01T00:00:00Z","project":[{"grant_number":"801770","_id":"2688CF98-B435-11E9-9278-68D0E5697425","name":"Angulon: physics and applications of a new quasiparticle","call_identifier":"H2020"},{"call_identifier":"H2020","name":"ISTplus - Postdoctoral Fellowships","_id":"260C2330-B435-11E9-9278-68D0E5697425","grant_number":"754411"}]},{"publication_identifier":{"issn":["1432-5411"]},"month":"02","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","file":[{"date_created":"2024-03-04T07:07:10Z","date_updated":"2024-03-04T07:07:10Z","success":1,"file_id":"15049","file_name":"2024_FewBodySys_Varshney.pdf","checksum":"c4e08cc7bc756da69b1b36fda7bb92fb","content_type":"application/pdf","file_size":436712,"access_level":"open_access","relation":"main_file","creator":"dernst"}],"oa_version":"Published Version","day":"17","arxiv":1,"author":[{"first_name":"Atul","full_name":"Varshney, Atul","orcid":"0000-0002-3072-5999","id":"2A2006B2-F248-11E8-B48F-1D18A9856A87","last_name":"Varshney"},{"orcid":"0000-0001-9666-3543","id":"4AF46FD6-F248-11E8-B48F-1D18A9856A87","last_name":"Ghazaryan","first_name":"Areg","full_name":"Ghazaryan, Areg"},{"orcid":"0000-0003-0393-5525","id":"37D278BC-F248-11E8-B48F-1D18A9856A87","last_name":"Volosniev","first_name":"Artem","full_name":"Volosniev, Artem"}],"type":"journal_article","status":"public","intvolume":"        65","has_accepted_license":"1","scopus_import":"1","article_processing_charge":"Yes (via OA deal)","date_updated":"2024-03-04T07:08:16Z","oa":1,"title":"Classical ‘spin’ filtering with two degrees of freedom and dissipation","publication":"Few-Body Systems","language":[{"iso":"eng"}],"tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)","image":"/images/cc_by.png","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"ddc":["530"],"abstract":[{"lang":"eng","text":"Coupling of orbital motion to a spin degree of freedom gives rise to various transport phenomena in quantum systems that are beyond the standard paradigms of classical physics.

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."}],"external_id":{"arxiv":["2203.09443"],"isi":["000982435900002"]},"publication_status":"published","doi":"10.1103/physrevlett.130.106901","_id":"12723","article_type":"original","article_number":"106901","keyword":["General Physics and Astronomy"],"date_created":"2023-03-14T13:11:59Z","citation":{"ama":"Volosniev A, Shiva Kumar A, Lorenc D, et al.

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."}],"external_id":{"isi":["001022811500001"],"arxiv":["2304.14198"]},"tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)","image":"/images/cc_by.png","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"ddc":["530"],"publication_status":"published","quality_controlled":"1","volume":14,"page":"6309-6314","department":[{"_id":"MiLe"},{"_id":"ZhAl"}],"date_published":"2023-07-05T00:00:00Z","publisher":"American Chemical Society","project":[{"grant_number":"801770","_id":"2688CF98-B435-11E9-9278-68D0E5697425","name":"Angulon: physics and applications of a new quasiparticle","call_identifier":"H2020"}]},{"department":[{"_id":"MiLe"}],"date_published":"2023-04-19T00:00:00Z","status":"public","type":"research_data_reference","publisher":"SciPost Foundation","project":[{"name":"ISTplus - Postdoctoral Fellowships","call_identifier":"H2020","grant_number":"754411","_id":"260C2330-B435-11E9-9278-68D0E5697425"}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","abstract":[{"text":"We introduce a generic and accessible implementation of an exact diagonalization method for studying few-fermion models.

Already for a few particles we find a ground-state level crossing between sectors with different fermion parities.

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"}],"publication_status":"published","publication":"Proceedings of the National Academy of Sciences of the United States of America","language":[{"iso":"eng"}],"has_accepted_license":"1","scopus_import":"1","intvolume":"       120","date_updated":"2023-10-17T11:45:25Z","oa":1,"article_processing_charge":"Yes (in subscription journal)","issue":"32","title":"Nuclear spin effects in biological processes","pmid":1,"status":"public","type":"journal_article","month":"07","publication_identifier":{"eissn":["1091-6490"]},"oa_version":"Published Version","day":"31","file":[{"date_created":"2023-08-14T07:43:45Z","date_updated":"2023-08-14T07:43:45Z","success":1,"checksum":"a5ed64788a5acef9b9a300a26fa5a177","file_id":"14047","file_name":"2023_PNAS_Vardi.pdf","file_size":1003092,"content_type":"application/pdf","relation":"main_file","access_level":"open_access","creator":"dernst"}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","author":[{"last_name":"Vardi","first_name":"Ofek","full_name":"Vardi, Ofek"},{"last_name":"Maroudas-Sklare","full_name":"Maroudas-Sklare, Naama","first_name":"Naama"},{"last_name":"Kolodny","first_name":"Yuval","full_name":"Kolodny, Yuval"},{"first_name":"Artem","full_name":"Volosniev, Artem","orcid":"0000-0003-0393-5525","id":"37D278BC-F248-11E8-B48F-1D18A9856A87","last_name":"Volosniev"},{"last_name":"Saragovi","full_name":"Saragovi, Amijai","first_name":"Amijai"},{"first_name":"Nir","full_name":"Galili, Nir","last_name":"Galili"},{"full_name":"Ferrera, Stav","first_name":"Stav","last_name":"Ferrera"},{"full_name":"Ghazaryan, Areg","first_name":"Areg","orcid":"0000-0001-9666-3543","id":"4AF46FD6-F248-11E8-B48F-1D18A9856A87","last_name":"Ghazaryan"},{"full_name":"Yuran, Nir","first_name":"Nir","last_name":"Yuran"},{"first_name":"Hagit P.","full_name":"Affek, Hagit P.","last_name":"Affek"},{"last_name":"Luz","first_name":"Boaz","full_name":"Luz, Boaz"},{"last_name":"Goldsmith","full_name":"Goldsmith, Yonaton","first_name":"Yonaton"},{"last_name":"Keren","first_name":"Nir","full_name":"Keren, Nir"},{"last_name":"Yochelis","full_name":"Yochelis, Shira","first_name":"Shira"},{"first_name":"Itay","full_name":"Halevy, Itay","last_name":"Halevy"},{"full_name":"Lemeshko, Mikhail","first_name":"Mikhail","orcid":"0000-0002-6990-7802","last_name":"Lemeshko","id":"37CB05FA-F248-11E8-B48F-1D18A9856A87"},{"first_name":"Yossi","full_name":"Paltiel, Yossi","last_name":"Paltiel"}]},{"type":"journal_article","status":"public","arxiv":1,"author":[{"first_name":"Fabian","full_name":"Brauneis, Fabian","last_name":"Brauneis"},{"first_name":"Areg","full_name":"Ghazaryan, Areg","orcid":"0000-0001-9666-3543","id":"4AF46FD6-F248-11E8-B48F-1D18A9856A87","last_name":"Ghazaryan"},{"last_name":"Hammer","first_name":"Hans-Werner","full_name":"Hammer, Hans-Werner"},{"orcid":"0000-0003-0393-5525","last_name":"Volosniev","id":"37D278BC-F248-11E8-B48F-1D18A9856A87","first_name":"Artem","full_name":"Volosniev, Artem"}],"month":"08","publication_identifier":{"issn":["2399-3650"]},"file":[{"file_id":"14268","checksum":"6edfc59b0ee7dc406d0968b05236e83d","file_name":"2023_CommPhysics_Brauneis.pdf","success":1,"date_updated":"2023-09-05T08:45:49Z","date_created":"2023-09-05T08:45:49Z","creator":"dernst","file_size":855960,"content_type":"application/pdf","access_level":"open_access","relation":"main_file"}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","day":"22","oa_version":"Published Version","language":[{"iso":"eng"}],"publication":"Communications Physics","article_processing_charge":"Yes (via OA deal)","date_updated":"2023-12-13T12:21:09Z","oa":1,"title":"Emergence of a Bose polaron in a small ring threaded by the Aharonov-Bohm flux","isi":1,"scopus_import":"1","has_accepted_license":"1","intvolume":"         6","date_published":"2023-08-22T00:00:00Z","publisher":"Springer Nature","volume":6,"quality_controlled":"1","department":[{"_id":"MiLe"}],"publication_status":"published","tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)","image":"/images/cc_by.png","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"ddc":["530"],"abstract":[{"lang":"eng","text":"The model of a ring threaded by the Aharonov-Bohm flux underlies our understanding of a coupling between gauge potentials and matter.

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"}],"external_id":{"arxiv":["2202.11071"]},"project":[{"name":"ISTplus - Postdoctoral Fellowships","call_identifier":"H2020","grant_number":"754411","_id":"260C2330-B435-11E9-9278-68D0E5697425"}],"date_published":"2023-11-29T00:00:00Z","publisher":"Elsevier","quality_controlled":"1","volume":1042,"page":"1-108","department":[{"_id":"MiLe"}],"year":"2023","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.

First, we derive mean-field solutions to the problem on a finite ring for the two asymptotic cases: (i) all bosons are bound to the impurity and (ii) all bosons are in a scattering state. 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. Our findings are important for understanding such artificial atoms in low-density Bose gases with static and mobile impurities.","lang":"eng"}],"publication_status":"published","publisher":"IOP Publishing","date_published":"2022-06-01T00:00:00Z","department":[{"_id":"MiLe"}],"quality_controlled":"1","volume":24,"project":[{"call_identifier":"H2020","name":"ISTplus - Postdoctoral Fellowships","grant_number":"754411","_id":"260C2330-B435-11E9-9278-68D0E5697425"},{"name":"Angulon: physics and applications of a new quasiparticle","call_identifier":"H2020","grant_number":"801770","_id":"2688CF98-B435-11E9-9278-68D0E5697425"}],"isi":1,"has_accepted_license":"1","scopus_import":"1","intvolume":"        24","oa":1,"date_updated":"2023-08-03T11:57:41Z","issue":"6","article_processing_charge":"No","title":"Artificial atoms from cold bosons in one dimension","publication":"New Journal of Physics","language":[{"iso":"eng"}],"month":"06","publication_identifier":{"issn":["1367-2630"]},"oa_version":"Published Version","day":"01","file":[{"date_created":"2022-07-18T06:33:13Z","date_updated":"2022-07-18T06:33:13Z","success":1,"file_id":"11594","checksum":"dc67b60f2e50e9ef2bd820ca0d7333d2","file_name":"2022_NewJournalPhysics_Brauneis.pdf","relation":"main_file","access_level":"open_access","content_type":"application/pdf","file_size":3415721,"creator":"dernst"}],"user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","author":[{"full_name":"Brauneis, Fabian","first_name":"Fabian","last_name":"Brauneis"},{"first_name":"Timothy G.","full_name":"Backert, Timothy G.","last_name":"Backert"},{"full_name":"Mistakidis, Simeon I.","first_name":"Simeon I.","last_name":"Mistakidis"},{"full_name":"Lemeshko, Mikhail","first_name":"Mikhail","id":"37CB05FA-F248-11E8-B48F-1D18A9856A87","last_name":"Lemeshko","orcid":"0000-0002-6990-7802"},{"last_name":"Hammer","first_name":"Hans Werner","full_name":"Hammer, Hans Werner"},{"id":"37D278BC-F248-11E8-B48F-1D18A9856A87","last_name":"Volosniev","orcid":"0000-0003-0393-5525","full_name":"Volosniev, Artem","first_name":"Artem"}],"status":"public","type":"journal_article"},{"status":"public","type":"journal_article","month":"02","publication_identifier":{"issn":["2542-4653"]},"file":[{"success":1,"checksum":"9fd614b7ab49999e7267874df2582f7e","file_name":"2021_SciPostPhysics_Marchukov.pdf","file_id":"9105","date_created":"2021-02-09T07:06:22Z","date_updated":"2021-02-09T07:06:22Z","creator":"dernst","access_level":"open_access","relation":"main_file","content_type":"application/pdf","file_size":666512}],"user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","day":"03","oa_version":"Published Version","arxiv":1,"author":[{"last_name":"Marchukov","full_name":"Marchukov, Oleksandr","first_name":"Oleksandr"},{"last_name":"Volosniev","id":"37D278BC-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0003-0393-5525","full_name":"Volosniev, Artem","first_name":"Artem"}],"publication":"SciPost Physics","language":[{"iso":"eng"}],"isi":1,"intvolume":"        10","has_accepted_license":"1","article_processing_charge":"No","issue":"2","date_updated":"2023-08-07T13:39:37Z","oa":1,"title":"Shape of a sound wave in a weakly-perturbed Bose gas","date_published":"2021-02-03T00:00:00Z","publisher":"SciPost Foundation","quality_controlled":"1","volume":10,"department":[{"_id":"MiLe"}],"project":[{"call_identifier":"H2020","name":"ISTplus - Postdoctoral Fellowships","_id":"260C2330-B435-11E9-9278-68D0E5697425","grant_number":"754411"}],"tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)","image":"/images/cc_by.png","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"ddc":["530"],"abstract":[{"lang":"eng","text":"We employ the Gross-Pitaevskii equation to study acoustic emission generated in a uniform Bose gas by a static impurity.

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"}],"ddc":["530"],"tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)","image":"/images/cc_by.png","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"publication_status":"published","doi":"10.1038/s42005-021-00753-7","file_date_updated":"2021-12-06T14:53:41Z","article_type":"original","_id":"10401","ec_funded":1,"article_number":"252","citation":{"chicago":"Barfknecht, Rafael E., Angela Foerster, Nikolaj T.

Depending on the ratio κ of the impurity and fermion masses, the billiards can be integrable or non-integrable (also referred to in the main text as chaotic). 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"}],"external_id":{"isi":["000664736300001"],"arxiv":["2102.04961"]},"article_type":"original","_id":"9679","file_date_updated":"2021-07-19T11:47:16Z","doi":"10.1088/1367-2630/ac0576","year":"2021","acknowledgement":"We thank Aidan Tracy for his input during the initial stages of this project.
