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"}],"intvolume":" 109","status":"public","title":"Linear rotor in an ideal Bose gas near the threshold for binding","_id":"14845","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","oa_version":"None","scopus_import":"1","article_processing_charge":"No","day":"01","article_type":"original","citation":{"mla":"Dome, Tibor, et al. “Linear Rotor in an Ideal Bose Gas near the Threshold for Binding.” Physical Review B, vol. 109, no. 1, 014102, American Physical Society, 2024, doi:10.1103/PhysRevB.109.014102.","short":"T.

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"}],"issue":"1"},{"date_published":"2023-03-10T00:00:00Z","publication":"Physical Review Letters","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.","short":"V.

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.","lang":"eng"}],"issue":"10","type":"journal_article","doi":"10.1103/PhysRevLett.130.103202","language":[{"iso":"eng"}],"main_file_link":[{"open_access":"1","url":"https://doi.org/10.48550/arXiv.2206.07067"}],"oa":1,"external_id":{"isi":["000957635500003"],"arxiv":["2206.07067"]},"isi":1,"quality_controlled":"1","project":[{"grant_number":"801770","_id":"2688CF98-B435-11E9-9278-68D0E5697425","call_identifier":"H2020","name":"Angulon: physics and applications of a new quasiparticle"}],"month":"03","publication_identifier":{"issn":["0031-9007"],"eissn":["1079-7114"]},"author":[{"full_name":"Karle, Volker","id":"D7C012AE-D7ED-11E9-95E8-1EC5E5697425","first_name":"Volker","last_name":"Karle"},{"id":"4AF46FD6-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-9666-3543","first_name":"Areg","last_name":"Ghazaryan","full_name":"Ghazaryan, Areg"},{"first_name":"Mikhail","last_name":"Lemeshko","id":"37CB05FA-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-6990-7802","full_name":"Lemeshko, Mikhail"}],"related_material":{"link":[{"url":"https://ista.ac.at/en/news/topology-of-rotating-molecules/","description":"News on the ISTA website","relation":"press_release"}]},"date_updated":"2023-08-01T14:02:06Z","date_created":"2023-04-02T22:01:10Z","volume":130,"acknowledgement":"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."}],"issue":"10","_id":"12790","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","status":"public","title":"Multilayer graphenes as a platform for interaction-driven physics and topological superconductivity","intvolume":" 107","oa_version":"Preprint","month":"03","publication_identifier":{"eissn":["2469-9969"],"issn":["2469-9950"]},"external_id":{"arxiv":["2211.02492"],"isi":["000945526400003"]},"main_file_link":[{"url":"https://doi.org/10.48550/arXiv.2211.02492","open_access":"1"}],"oa":1,"quality_controlled":"1","isi":1,"doi":"10.1103/PhysRevB.107.104502","language":[{"iso":"eng"}],"article_number":"104502","year":"2023","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.","publication_status":"published","department":[{"_id":"MaSe"},{"_id":"MiLe"}],"publisher":"American Physical Society","author":[{"orcid":"0000-0001-9666-3543","id":"4AF46FD6-F248-11E8-B48F-1D18A9856A87","last_name":"Ghazaryan","first_name":"Areg","full_name":"Ghazaryan, Areg"},{"full_name":"Holder, Tobias","last_name":"Holder","first_name":"Tobias"},{"last_name":"Berg","first_name":"Erez","full_name":"Berg, Erez"},{"full_name":"Serbyn, Maksym","id":"47809E7E-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-2399-5827","first_name":"Maksym","last_name":"Serbyn"}],"related_material":{"link":[{"url":"https://ista.ac.at/en/news/reaching-superconductivity-layer-by-layer/","description":"News on the ISTA website","relation":"press_release"}]},"date_created":"2023-04-02T22:01:10Z","date_updated":"2023-08-01T13:59:29Z","volume":107},{"year":"2023","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.","publisher":"American Physical Society","department":[{"_id":"MaSe"},{"_id":"ChLa"},{"_id":"MiLe"}],"publication_status":"published","author":[{"full_name":"Henderson, Paul M","first_name":"Paul M","last_name":"Henderson","id":"13C09E74-18D9-11E9-8878-32CFE5697425","orcid":"0000-0002-5198-7445"},{"orcid":"0000-0001-9666-3543","id":"4AF46FD6-F248-11E8-B48F-1D18A9856A87","last_name":"Ghazaryan","first_name":"Areg","full_name":"Ghazaryan, Areg"},{"full_name":"Zibrov, Alexander A.","first_name":"Alexander A.","last_name":"Zibrov"},{"last_name":"Young","first_name":"Andrea F.","full_name":"Young, Andrea F."},{"last_name":"Serbyn","first_name":"Maksym","orcid":"0000-0002-2399-5827","id":"47809E7E-F248-11E8-B48F-1D18A9856A87","full_name":"Serbyn, Maksym"}],"volume":108,"date_created":"2023-09-12T07:12:12Z","date_updated":"2023-09-20T09:38:24Z","article_number":"125411","main_file_link":[{"open_access":"1","url":"https://doi.org/10.48550/arXiv.2210.06310"}],"external_id":{"arxiv":["2210.06310"]},"oa":1,"quality_controlled":"1","doi":"10.1103/physrevb.108.125411","language":[{"iso":"eng"}],"publication_identifier":{"issn":["2469-9950"],"eissn":["2469-9969"]},"month":"09","_id":"14320","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","intvolume":" 108","status":"public","title":"Deep learning extraction of band structure parameters from density of states: A case study on trilayer graphene","oa_version":"Preprint","type":"journal_article","issue":"12","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."}],"citation":{"chicago":"Henderson, Paul M, Areg Ghazaryan, Alexander A.

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."}],"type":"journal_article"},{"department":[{"_id":"MiLe"}],"publisher":"National Academy of Sciences","publication_status":"published","pmid":1,"acknowledgement":"N.M.-S. acknowledges the support of the Ministry of Energy, Israel, as part of the scholarship program for graduate students in the fields of energy.

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.

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."}],"type":"journal_article","file":[{"access_level":"open_access","file_name":"2023_CommPhysics_Brauneis.pdf","creator":"dernst","file_size":855960,"content_type":"application/pdf","file_id":"14268","relation":"main_file","success":1,"checksum":"6edfc59b0ee7dc406d0968b05236e83d","date_created":"2023-09-05T08:45:49Z","date_updated":"2023-09-05T08:45:49Z"}],"oa_version":"Published Version","status":"public","ddc":["530"],"title":"Emergence of a Bose polaron in a small ring threaded by the Aharonov-Bohm flux","intvolume":" 6","_id":"14246","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","month":"08","publication_identifier":{"issn":["2399-3650"]},"language":[{"iso":"eng"}],"doi":"10.1038/s42005-023-01281-2","isi":1,"quality_controlled":"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"},"oa":1,"external_id":{"isi":["001052577500002"],"arxiv":["2301.10488"]},"file_date_updated":"2023-09-05T08:45:49Z","article_number":"224","date_created":"2023-08-28T12:36:49Z","date_updated":"2023-12-13T12:21:09Z","volume":6,"author":[{"first_name":"Fabian","last_name":"Brauneis","full_name":"Brauneis, Fabian"},{"first_name":"Areg","last_name":"Ghazaryan","id":"4AF46FD6-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-9666-3543","full_name":"Ghazaryan, Areg"},{"full_name":"Hammer, Hans-Werner","last_name":"Hammer","first_name":"Hans-Werner"},{"id":"37D278BC-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0003-0393-5525","first_name":"Artem","last_name":"Volosniev","full_name":"Volosniev, Artem"}],"publication_status":"published","publisher":"Springer Nature","department":[{"_id":"MiLe"}],"acknowledgement":"Open Access funding enabled and organized by Projekt DEAL.\r\nWe would like to thank Jonas Jager for sharing his data with us in the early stages of this project.

For instance, upon applying a perpendicular electric field, its band structure exhibits several off-center Dirac points (so-called Dirac gullies) in each valley. Here, the formation of Dirac gullies and the interaction-induced breakdown of gully coherence is explored via magnetotransport measurements in high-quality Bernal-stacked (ABA) trilayer graphene. At zero magnetic field, multiple Lifshitz transitions indicating the formation of Dirac gullies are identified. In the quantum Hall regime, the emergence of Dirac gullies is evident as an increase in Landau level degeneracy. When tuning both electric and magnetic fields, electron–electron interactions can be controllably enhanced until, beyond critical electric and magnetic fields, the gully degeneracy is eventually lifted. The arising correlated ground state is consistent with a previously predicted nematic phase that spontaneously breaks the rotational gully symmetry."}],"type":"journal_article","date_published":"2022-04-27T00:00:00Z","page":"3317-3322","article_type":"original","citation":{"ista":"Winterer F, Seiler AM, Ghazaryan A, Geisenhof FR, Watanabe K, Taniguchi T, Serbyn M, Weitz RT. 2022.

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."}],"article_type":"original","publication":"Nature","citation":{"ama":"Zhou H, Xie T, Ghazaryan A, et al.

Superconductivity is strongly enhanced when the inner and outer Fermi surfaces are close to each other. The most prevalent state has chiral p-wave symmetry, but d-wave and extended s-wave pairing are also possible. We discuss these results in the context of rhombohedral trilayer graphene, where superconductivity was recently discovered in regimes where the normal state has an annular Fermi surface. Using realistic parameters, our mechanism can account for the order of magnitude of Tc, as well as its trends as a function of electron density and perpendicular displacement field. Moreover, it naturally explains some of the outstanding puzzles in this material, that include the weak temperature dependence of the resistivity above Tc, and the proximity of spin singlet superconductivity to the ferromagnetic phase."}]},{"language":[{"iso":"eng"}],"doi":"10.1088/1367-2630/ac4124","project":[{"name":"ISTplus - Postdoctoral Fellowships","call_identifier":"H2020","_id":"260C2330-B435-11E9-9278-68D0E5697425","grant_number":"754411"}],"isi":1,"quality_controlled":"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"},"external_id":{"arxiv":["2012.11625"],"isi":["000734063700001"]},"oa":1,"publication_identifier":{"issn":["1367-2630"]},"month":"12","volume":23,"date_updated":"2023-08-17T06:54:54Z","date_created":"2022-01-16T23:01:28Z","author":[{"full_name":"Ghazaryan, Areg","orcid":"0000-0001-9666-3543","id":"4AF46FD6-F248-11E8-B48F-1D18A9856A87","last_name":"Ghazaryan","first_name":"Areg"},{"full_name":"Nica, Emilian M.","first_name":"Emilian M.","last_name":"Nica"},{"full_name":"Erten, Onur","last_name":"Erten","first_name":"Onur"},{"last_name":"Ghaemi","first_name":"Pouyan","full_name":"Ghaemi, Pouyan"}],"publisher":"IOP Publishing","department":[{"_id":"MiLe"}],"publication_status":"published","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"}],"type":"journal_article"},{"date_published":"2021-07-08T00:00:00Z","language":[{"iso":"eng"}],"acknowledged_ssus":[{"_id":"M-Shop"},{"_id":"NanoFab"}],"external_id":{"arxiv":["2107.03695"]},"citation":{"chicago":"Phan, Duc T, Jorden L Senior, Areg Ghazaryan, M.

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."}],"type":"preprint","article_number":"2107.03695"},{"file_date_updated":"2020-10-14T15:16:28Z","ec_funded":1,"article_number":"178","author":[{"full_name":"Ghazaryan, Areg","first_name":"Areg","last_name":"Ghazaryan","id":"4AF46FD6-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-9666-3543"},{"full_name":"Lemeshko, Mikhail","id":"37CB05FA-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-6990-7802","first_name":"Mikhail","last_name":"Lemeshko"},{"first_name":"Artem","last_name":"Volosniev","id":"37D278BC-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0003-0393-5525","full_name":"Volosniev, Artem"}],"date_created":"2020-10-13T09:48:59Z","date_updated":"2023-08-22T09:58:46Z","volume":3,"acknowledgement":"This work has received funding from the European Union’s Horizon 2020 research and innovation program under the Marie Skłodowska-Curie Grant Agreement No. 754411 (A.G.V. and A.G.).

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"}],"type":"journal_article","oa_version":"Published Version","file":[{"creator":"dernst","content_type":"application/pdf","file_size":1462934,"file_name":"2020_CommPhysics_Ghazaryan.pdf","access_level":"open_access","date_updated":"2020-10-14T15:16:28Z","date_created":"2020-10-14T15:16:28Z","success":1,"checksum":"60cd35b99f0780acffc7b6060e49ec8b","file_id":"8662","relation":"main_file"}],"_id":"8652","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","ddc":["530"],"status":"public","title":"Filtering spins by scattering from a lattice of point magnets","intvolume":" 3","day":"09","article_processing_charge":"Yes","has_accepted_license":"1","scopus_import":"1","date_published":"2020-10-09T00:00:00Z","publication":"Communications Physics","citation":{"short":"A.
