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."}],"issue":"12","status":"public","title":"Shadow surface states in topological Kondo insulators","ddc":["530"],"intvolume":" 23","_id":"10628","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","file":[{"date_created":"2022-01-17T10:01:58Z","date_updated":"2022-01-17T10:01:58Z","success":1,"checksum":"0c3cb6816242fa8afd1cc87a5fe77821","file_id":"10632","relation":"main_file","creator":"cchlebak","content_type":"application/pdf","file_size":2533102,"file_name":"2021_NewJourPhys_Ghazaryan.pdf","access_level":"open_access"}],"oa_version":"Published Version","month":"12","publication_identifier":{"issn":["1367-2630"]},"isi":1,"quality_controlled":"1","project":[{"grant_number":"754411","_id":"260C2330-B435-11E9-9278-68D0E5697425","name":"ISTplus - Postdoctoral Fellowships","call_identifier":"H2020"}],"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":{"isi":["000734063700001"],"arxiv":["2012.11625"]},"oa":1,"language":[{"iso":"eng"}],"doi":"10.1088/1367-2630/ac4124","article_number":"123042","file_date_updated":"2022-01-17T10:01:58Z","ec_funded":1,"publication_status":"published","department":[{"_id":"MiLe"}],"publisher":"IOP Publishing","year":"2021","acknowledgement":"PG acknowledges support from National Science Foundation Awards No. DMR-1824265 for this work.

So far, however, it has proven challenging to deal with microscopic models in which the total number of particles is not conserved. To address this issue, we propose a new variant of neural network states, which we term neural coherent states. Taking the Fröhlich impurity model as a case study, we show that neural coherent states can learn the ground state of non-additive systems very well. In particular, we observe substantial improvement over the standard coherent state estimates in the most challenging intermediate coupling regime. Our approach is generic and does not assume specific details of the system, suggesting wide applications.","lang":"eng"}],"type":"preprint"},{"type":"preprint","article_number":"2107.03695","ec_funded":1,"abstract":[{"text":"Superconductor-semiconductor hybrids are platforms for realizing effective p-wave superconductivity. 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"}],"year":"2021","_id":"10029","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","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 investigate how the spin-orbital entanglement in a Mott insulator depends on the value of the spin-orbit coupling of the relativistic origin. To this end, we numerically diagonalize a one-dimensional spin-orbital model with Kugel-Khomskii exchange interactions between spins and orbitals on different sites supplemented by the on-site spin-orbit coupling. In the regime of small spin-orbit coupling with regard to the spin-orbital exchange, the ground state to a large extent resembles the one obtained in the limit of vanishing spin-orbit coupling. On the other hand, for large spin-orbit coupling the ground state can, depending on the model parameters, either still show negligible spin-orbital entanglement or evolve to a highly spin-orbitally-entangled phase with completely distinct properties that are described by an effective XXZ model. The presented results suggest that (i) the spin-orbital entanglement may be induced by large on-site spin-orbit coupling, as found in the 5d transition metal oxides, such as the iridates; (ii) for Mott insulators with weak spin-orbit coupling of Ising type, such as, e.g., the alkali hyperoxides, the effects of the spin-orbit coupling on the ground state can, in the first order of perturbation theory, be neglected."}],"issue":"1","article_type":"original","publication":"Physical Review Research","citation":{"ama":"Gotfryd D, Paerschke E, Chaloupka J, Oles AM, Wohlfeld K.

The input for our calculations—the energies of few-body clusters—is estimated using the harmonic approximation. We first describe and demonstrate the validity of our numerical procedure. Then we discuss the results featuring melting of the zero-temperature many-body state into a gas of free particles and few-body clusters. For temperature higher than its binding energy threshold, the dimers overwhelmingly dominate the ensemble, where the remaining probability is in free particles. At very high temperatures free (harmonic oscillator trap-bound) particle dominance is eventually reached.

By considering the recently introduced rotating polaron problem, we define the Hamiltonian and examine the energy spectrum. The weak-coupling regime is studied by means of a variational ansatz in the truncated Fock space. The corresponding spectrum indicates that there emerges a coupling between the internal and orbital angular momenta of the impurity as a consequence of the phonon exchange. We interpret the coupling as a phonon-mediated spin-orbit coupling and quantify it by using a correlation function between the internal and the orbital angular momentum operators. The strong-coupling regime is investigated within the Pekar approach, and it is shown that the correlation function of the ground state shows a kink at a critical coupling, that is explained by a sharp transition from the noninteracting state to the states that exhibit strong interaction with the surroundings. The results might find applications in such fields as spintronics or topological insulators where spin-orbit coupling is of crucial importance.","lang":"eng"}],"issue":"18","type":"journal_article"},{"project":[{"_id":"26031614-B435-11E9-9278-68D0E5697425","grant_number":"P29902","name":"Quantum rotations in the presence of a many-body environment","call_identifier":"FWF"},{"call_identifier":"H2020","name":"Angulon: physics and applications of a new quasiparticle","_id":"2688CF98-B435-11E9-9278-68D0E5697425","grant_number":"801770"},{"name":"A path-integral approach to composite impurities","call_identifier":"FWF","_id":"26986C82-B435-11E9-9278-68D0E5697425","grant_number":"M02641"},{"_id":"2564DBCA-B435-11E9-9278-68D0E5697425","grant_number":"665385","name":"International IST Doctoral Program","call_identifier":"H2020"}],"quality_controlled":"1","isi":1,"oa":1,"main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/2006.02694"}],"external_id":{"arxiv":["2006.02694"],"isi":["000544526900006"]},"language":[{"iso":"eng"}],"doi":"10.1103/PhysRevLett.125.013001","publication_identifier":{"eissn":["10797114"],"issn":["00319007"]},"month":"07","department":[{"_id":"MiLe"}],"publisher":"American Physical Society","publication_status":"published","acknowledgement":"H.

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"}],"title":"Filtering spins by scattering from a lattice of point magnets","ddc":["530"],"status":"public","intvolume":" 3","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","_id":"8652","oa_version":"Published Version","file":[{"date_updated":"2020-10-14T15:16:28Z","date_created":"2020-10-14T15:16:28Z","success":1,"checksum":"60cd35b99f0780acffc7b6060e49ec8b","file_id":"8662","relation":"main_file","creator":"dernst","file_size":1462934,"content_type":"application/pdf","file_name":"2020_CommPhysics_Ghazaryan.pdf","access_level":"open_access"}],"scopus_import":"1","day":"09","article_processing_charge":"Yes","has_accepted_license":"1","article_type":"original","publication":"Communications Physics","citation":{"chicago":"Ghazaryan, Areg, Mikhail Lemeshko, and Artem Volosniev. “Filtering Spins by Scattering from a Lattice of Point Magnets.” Communications Physics.

We use epitaxial strain to modify the Ir–O bond geometry in Sr2IrO4 and perform momentum-dependent resonant inelastic X-ray scattering (RIXS) at the metal and at the ligand sites to unveil the response of the low-energy elementary excitations. We observe that the pseudospin-wave dispersion for tensile-strained Sr2IrO4 films displays large softening along the [h,0] direction, while along the [h,h] direction it shows hardening. This evolution reveals a renormalization of the magnetic interactions caused by a strain-driven cross-over from anisotropic to isotropic interactions between the magnetic moments. Moreover, we detect dispersive electron–hole pair excitations which shift to lower (higher) energies upon compressive (tensile) strain, manifesting a reduction (increase) in the size of the charge gap. This behavior shows an intimate coupling between charge excitations and lattice distortions in Sr2IrO4, originating from the modified hopping elements between the t2g orbitals. Our work highlights the central role played by the lattice degrees of freedom in determining both the pseudospin and charge excitations of Sr2IrO4 and provides valuable information toward the control of the ground state of complex oxides in the presence of high spin–orbit coupling."}],"type":"journal_article","file":[{"success":1,"checksum":"1638fa36b442e2868576c6dd7d6dc505","date_updated":"2020-10-28T11:53:12Z","date_created":"2020-10-28T11:53:12Z","file_id":"8715","relation":"main_file","creator":"cziletti","content_type":"application/pdf","file_size":1176522,"access_level":"open_access","file_name":"2020_PNAS_Paris.pdf"}],"oa_version":"Published Version","intvolume":" 117","title":"Strain engineering of the charge and spin-orbital interactions in Sr2IrO4","ddc":["530"],"status":"public","_id":"8699","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","has_accepted_license":"1","article_processing_charge":"No","day":"06","scopus_import":"1","date_published":"2020-10-06T00:00:00Z","page":"24764-24770","article_type":"original","citation":{"chicago":"Paris, Eugenio, Yi Tseng, Ekaterina Paerschke, Wenliang Zhang, Mary H Upton, Anna Efimenko, Katharina Rolfs, et al. “Strain Engineering of the Charge and Spin-Orbital Interactions in Sr2IrO4.” Proceedings of the National Academy of Sciences of the United States of America.

From that perspective, chiral molecules acting as efficient spin selectors pose a puzzle that attracted a lot of attention in recent years. Here, we revisit the physical origins of chiral-induced spin selectivity (CISS) and propose a simple analytic minimal model to describe it. The model treats a chiral molecule as an anisotropic wire with molecular dipole moments aligned arbitrarily with respect to the wire’s axes and is therefore quite general. Importantly, it shows that the helical structure of the molecule is not necessary to observe CISS and other chiral nonhelical molecules can also be considered as potential candidates for the CISS effect. We also show that the suggested simple model captures the main characteristics of CISS observed in the experiment, without the need for additional constraints employed in the previous studies. The results pave the way for understanding other related physical phenomena where the CISS effect plays an essential role."}],"intvolume":" 124","ddc":["530"],"status":"public","title":"Analytic model of chiral-induced spin selectivity","_id":"7968","user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","file":[{"date_created":"2020-10-20T14:39:47Z","date_updated":"2020-10-20T14:39:47Z","success":1,"checksum":"25932bb1d0b0a955be0bea4d17facd49","file_id":"8683","relation":"main_file","creator":"kschuh","content_type":"application/pdf","file_size":1543429,"file_name":"2020_PhysChemC_Ghazaryan.pdf","access_level":"open_access"}],"oa_version":"Published Version"},{"day":"21","article_processing_charge":"No","scopus_import":"1","date_published":"2020-07-21T00:00:00Z","article_type":"original","publication":"Physical Review B","citation":{"ista":"Hubert C, Cohen K, Ghazaryan A, Lemeshko M, Rapaport R, Santos PV. 2020.

Here, we theoretically study interactions between IXs in stacked DQW bilayers, where the dipolar coupling can be either attractive or repulsive depending on the relative positions of the particles. By using microscopic band structure calculations to determine the electronic states forming the excitons, we show that the attractive dipolar interaction between stacked IXs deforms their electronic wave function, thereby increasing the inter-DQW interaction energy and making the IX even more electrically polarizable. Many-particle interaction effects are addressed by considering the coupling between a single IX in one of the DQWs to a cloud of IXs in the other DQW, which is modeled either as a closed-packed lattice or as a continuum IX fluid. We find that the lattice model yields IX interlayer binding energies decreasing with increasing lattice density. This behavior is due to the dominating role of the intra-DQW dipolar repulsion, which prevents more than one exciton from entering the attractive region of the inter-DQW coupling. Finally, both models shows that the single IX distorts the distribution of IXs in the adjacent DQW, thus inducing the formation of an IX dipolar polaron (dipolaron). While the interlayer binding energy reduces with IX density for lattice dipolarons, the continuous polaron model predicts a nonmonotonous dependence on density in semiquantitative agreement with a recent experimental study [cf.

Although anyons are predicted to be realized in certain fractional quantum Hall systems, they have not yet been unambiguously detected in experiment. Here we introduce a simple quantum impurity model, where bosonic or fermionic impurities turn into anyons as a consequence of their interaction with the surrounding many-particle bath. A cloud of phonons dresses each impurity in such a way that it effectively attaches fluxes or vortices to it and thereby converts it into an Abelian anyon. The corresponding quantum impurity model, first, provides a different approach to the numerical solution of the many-anyon problem, along with a concrete perspective of anyons as emergent quasiparticles built from composite bosons or fermions. More importantly, the model paves the way toward realizing anyons using impurities in crystal lattices as well as ultracold gases. In particular, we consider two heavy electrons interacting with a two-dimensional lattice crystal in a magnetic field, and show that when the impurity-bath system is rotated at the cyclotron frequency, impurities behave as anyons as a consequence of the angular momentum exchange between the impurities and the bath. A possible experimental realization is proposed by identifying the statistics parameter in terms of the mean-square distance of the impurities and the magnetization of the impurity-bath system, both of which are accessible to experiment. Another proposed application is impurities immersed in a two-dimensional weakly interacting Bose gas."}],"user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","_id":"8769","intvolume":" 102","status":"public","title":"Quantum impurity model for anyons","oa_version":"Preprint","publication_identifier":{"eissn":["2469-9969"],"issn":["2469-9950"]},"month":"10","main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/1912.07890"}],"oa":1,"external_id":{"isi":["000582563300001"],"arxiv":["1912.07890"]},"project":[{"grant_number":"754411","_id":"260C2330-B435-11E9-9278-68D0E5697425","call_identifier":"H2020","name":"ISTplus - Postdoctoral Fellowships"},{"name":"Analysis of quantum many-body systems","call_identifier":"H2020","grant_number":"694227","_id":"25C6DC12-B435-11E9-9278-68D0E5697425"},{"call_identifier":"H2020","name":"Angulon: physics and applications of a new quasiparticle","grant_number":"801770","_id":"2688CF98-B435-11E9-9278-68D0E5697425"}],"quality_controlled":"1","isi":1,"doi":"10.1103/physrevb.102.144109","language":[{"iso":"eng"}],"article_number":"144109","ec_funded":1,"year":"2020","acknowledgement":"We are grateful to M.

We study this system in different parameter regimes and apply several theoretical approaches to describe its properties. Using a Born–Oppenheimer approximation, we investigate the dependence of the effective intermolecular interaction on the rotational state of the two molecules. In the strong-coupling regime, a product-state ansatz shows that the molecules tend to have a strong alignment in the ground state. To investigate the system in the weak-coupling regime, we apply a one-phonon excitation variational ansatz, which allows us to access the energy spectrum. In comparison to the angulon quasiparticle, the biangulon shows shifted angulon instabilities and an additional spectral instability, where resonant angular momentum transfer between the molecules and the bath takes place. These features are proposed as an experimentally observable signature for the formation of the biangulon quasiparticle.

A general question is whether new phases, not present in the uncoupled limit, may arise. We use machine learning and a suitable quasidistance between different points of the phase diagram to study layered spin models, in which the spin variables constituting each of the uncoupled systems (to which we refer as layers) are coupled to each other via an interlayer coupling. In such systems, in general, composite order parameters involving spins of different layers may emerge as a consequence of the interlayer coupling. We focus on the layered Ising and Ashkin–Teller models as a paradigmatic case study, determining their phase diagram via the application of a machine learning algorithm to the Monte Carlo data. Remarkably our technique is able to correctly characterize all the system phases also in the case of hidden order parameters, i.e. order parameters whose expression in terms of the microscopic configurations would require additional preprocessing of the data fed to the algorithm. We correctly retrieve the three known phases of the Ashkin–Teller model with ferromagnetic couplings, including the phase described by a composite order parameter. For the bilayer and trilayer Ising models the phases we find are only the ferromagnetic and the paramagnetic ones. Within the approach we introduce, owing to the construction of convolutional neural networks, naturally suitable for layered image-like data with arbitrary number of layers, no preprocessing of the Monte Carlo data is needed, also with regard to its spatial structure. The physical meaning of our results is discussed and compared with analytical data, where available. Yet, the method can be used without any a priori knowledge of the phases one seeks to find and can be applied to other models and structures.","lang":"eng"}],"user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","_id":"8644","intvolume":" 22","ddc":["530"],"title":"Detecting composite orders in layered models via machine learning","status":"public","oa_version":"Published Version","file":[{"creator":"dernst","file_size":2725143,"content_type":"application/pdf","file_name":"2020_NewJournalPhysics_Rzdkowski.pdf","access_level":"open_access","date_updated":"2020-10-12T12:18:47Z","date_created":"2020-10-12T12:18:47Z","success":1,"checksum":"c9238fff422e7a957c3a0d559f756b3a","file_id":"8650","relation":"main_file"}],"publication_identifier":{"issn":["13672630"]},"month":"09","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":["000573298000001"]},"project":[{"grant_number":"665385","_id":"2564DBCA-B435-11E9-9278-68D0E5697425","call_identifier":"H2020","name":"International IST Doctoral Program"},{"_id":"05A235A0-7A3F-11EA-A408-12923DDC885E","grant_number":"25681","name":"Analytic and machine learning approaches to composite quantum impurities"},{"grant_number":"M02641","_id":"26986C82-B435-11E9-9278-68D0E5697425","call_identifier":"FWF","name":"A path-integral approach to composite impurities"}],"isi":1,"quality_controlled":"1","doi":"10.1088/1367-2630/abae44","language":[{"iso":"eng"}],"article_number":"093026","ec_funded":1,"file_date_updated":"2020-10-12T12:18:47Z","acknowledgement":"We thank Gesualdo Delfino, Michele Fabrizio, Piero Ferrarese, Robert Konik, Christoph Lampert and Mikhail Lemeshko for stimulating discussions at various stages of this work.

Inspired by the possibility to experimentally manipulate and enhance chemical reactivity in helium nanodroplets, we investigate the rotation of coupled cold molecules in the presence of a many-body environment.\r\nIn this thesis, we introduce new variational approaches to quantum impurities and apply them to the Fröhlich polaron - a quasiparticle formed out of an electron (or other point-like impurity) in a polar medium, and to the angulon - a quasiparticle formed out of a rotating molecule in a bosonic bath.\r\nWith this theoretical toolbox, we reveal the self-localization transition for the angulon quasiparticle. We show that, unlike for polarons, self-localization of angulons occurs at finite impurity-bath coupling already at the mean-field level. The transition is accompanied by the spherical-symmetry breaking of the angulon ground state and a discontinuity in the first derivative of the ground-state energy. Moreover, the type of symmetry breaking is dictated by the symmetry of the microscopic impurity-bath interaction, which leads to a number of distinct self-localized states. \r\nFor the system containing multiple impurities, by analogy with the bipolaron, we introduce the biangulon quasiparticle describing two rotating molecules that align with respect to each other due to the effective attractive interaction mediated by the excitations of the bath. We study this system from the strong-coupling regime to the weak molecule-bath interaction regime. We show that the molecules tend to have a strong alignment in the ground state, the biangulon shows shifted angulon instabilities and an additional spectral instability, where resonant angular momentum transfer between the molecules and the bath takes place. Finally, we introduce a diagonalization scheme that allows us to describe the transition from two separated angulons to a biangulon as a function of the distance between the two molecules.","lang":"eng"}],"user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","_id":"8958","status":"public","ddc":["539"],"title":"Rotation of coupled cold molecules in the presence of a many-body environment","file":[{"file_size":3622305,"content_type":"application/pdf","creator":"xli","access_level":"open_access","file_name":"THESIS_Xiang_Li.pdf","checksum":"3994c54a1241451d561db1d4f43bad30","success":1,"date_created":"2020-12-22T10:55:56Z","date_updated":"2020-12-22T10:55:56Z","relation":"main_file","file_id":"8967"},{"access_level":"closed","file_name":"THESIS_Xiang_Li.zip","creator":"xli","content_type":"application/x-zip-compressed","file_size":4018859,"file_id":"8968","relation":"source_file","checksum":"0954ecfc5554c05615c14de803341f00","date_created":"2020-12-22T10:56:03Z","date_updated":"2020-12-30T07:18:03Z"}],"oa_version":"Published Version","day":"21","has_accepted_license":"1","article_processing_charge":"No","citation":{"ama":"Li X.
