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.

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."}],"has_accepted_license":"1","date_created":"2020-06-16T14:29:59Z","article_type":"original","volume":124,"title":"Analytic model of chiral-induced spin selectivity","oa_version":"Published Version","scopus_import":"1","day":"04","author":[{"orcid":"0000-0001-9666-3543","first_name":"Areg","id":"4AF46FD6-F248-11E8-B48F-1D18A9856A87","full_name":"Ghazaryan, Areg","last_name":"Ghazaryan"},{"full_name":"Paltiel, Yossi","last_name":"Paltiel","first_name":"Yossi"},{"orcid":"0000-0002-6990-7802","first_name":"Mikhail","id":"37CB05FA-F248-11E8-B48F-1D18A9856A87","full_name":"Lemeshko, Mikhail","last_name":"Lemeshko"}],"user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","citation":{"apa":"Ghazaryan, A., Paltiel, Y., &#38; Lemeshko, M.

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 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. Finally, by using products of single angulon and bare impurity wave functions as basis states, 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"}],"intvolume":"       152"},{"month":"07","arxiv":1,"department":[{"_id":"MiLe"}],"article_number":"045307","oa":1,"language":[{"iso":"eng"}],"issue":"4","citation":{"mla":"Hubert, C., et al. “Attractive Interactions, Molecular Complexes, and Polarons in Coupled Dipolar Exciton Fluids.” <i>Physical Review B</i>, vol. 102, no. 4, 045307, American Physical Society, 2020, doi:<a href=\"https://doi.org/10.1103/physrevb.102.045307\">10.1103/physrevb.102.045307</a>.","apa":"Hubert, C., Cohen, K., Ghazaryan, A., Lemeshko, M., Rapaport, R., &#38; Santos, P.

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. Hubert et al., Phys. Rev. X 9, 021026 (2019)].","lang":"eng"}],"publication_identifier":{"eissn":["2469-9969"],"issn":["2469-9950"]},"publication_status":"published","year":"2020","isi":1,"external_id":{"isi":["000550579100004"],"arxiv":["1910.06015"]},"project":[{"call_identifier":"FWF","name":"Quantum rotations in the presence of a many-body environment","grant_number":"P29902","_id":"26031614-B435-11E9-9278-68D0E5697425"},{"_id":"2688CF98-B435-11E9-9278-68D0E5697425","call_identifier":"H2020","grant_number":"801770","name":"Angulon: physics and applications of a new quasiparticle"},{"_id":"260C2330-B435-11E9-9278-68D0E5697425","name":"ISTplus - Postdoctoral Fellowships","grant_number":"754411","call_identifier":"H2020"}],"publication":"Physical Review B","status":"public","ec_funded":1,"date_published":"2020-07-21T00:00:00Z","acknowledgement":"We thank W.

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."}],"intvolume":"         3","volume":3,"date_created":"2020-10-13T09:48:59Z","article_type":"original","scopus_import":"1","day":"09","author":[{"first_name":"Areg","orcid":"0000-0001-9666-3543","last_name":"Ghazaryan","full_name":"Ghazaryan, Areg","id":"4AF46FD6-F248-11E8-B48F-1D18A9856A87"},{"first_name":"Mikhail","orcid":"0000-0002-6990-7802","last_name":"Lemeshko","id":"37CB05FA-F248-11E8-B48F-1D18A9856A87","full_name":"Lemeshko, Mikhail"},{"orcid":"0000-0003-0393-5525","first_name":"Artem","last_name":"Volosniev","id":"37D278BC-F248-11E8-B48F-1D18A9856A87","full_name":"Volosniev, Artem"}],"title":"Filtering spins by scattering from a lattice of point magnets","oa_version":"Published Version","citation":{"ama":"Ghazaryan A, Lemeshko M, Volosniev A.

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."}],"publication_identifier":{"issn":["2663-337X"]},"publication_status":"published","file_date_updated":"2020-12-30T07:18:03Z","author":[{"first_name":"Xiang","last_name":"Li","id":"4B7E523C-F248-11E8-B48F-1D18A9856A87","full_name":"Li, Xiang"}],"day":"21","title":"Rotation of coupled cold molecules in the presence of a many-body environment","oa_version":"Published Version","date_created":"2020-12-21T09:44:30Z","degree_awarded":"PhD","project":[{"call_identifier":"FWF","name":"Quantum rotations in the presence of a many-body environment","grant_number":"P29902","_id":"26031614-B435-11E9-9278-68D0E5697425"},{"name":"Angulon: physics and applications of a new quasiparticle","grant_number":"801770","call_identifier":"H2020","_id":"2688CF98-B435-11E9-9278-68D0E5697425"}],"status":"public","ec_funded":1,"date_published":"2020-12-21T00:00:00Z","year":"2020","related_material":{"record":[{"relation":"part_of_dissertation","status":"public","id":"5886"},{"status":"public","relation":"part_of_dissertation","id":"1120"},{"status":"public","relation":"part_of_dissertation","id":"8587"}]},"page":"125","ddc":["539"],"doi":"10.15479/AT:ISTA:8958","article_processing_charge":"No","alternative_title":["ISTA Thesis"],"publisher":"Institute of Science and Technology Austria","date_updated":"2024-08-07T07:16:53Z","_id":"8958","type":"dissertation"},{"project":[{"call_identifier":"FWF","name":"Quantum rotations in the presence of a many-body environment","grant_number":"P29902","_id":"26031614-B435-11E9-9278-68D0E5697425"}],"publication":"Physical Review X","status":"public","date_published":"2019-05-08T00:00:00Z","isi":1,"year":"2019","external_id":{"arxiv":["1807.11238"],"isi":["000467402900001"]},"ddc":["530"],"quality_controlled":"1","doi":"10.1103/PhysRevX.9.021026","article_processing_charge":"No","publisher":"American Physical Society","date_updated":"2024-02-28T13:12:48Z","_id":"6786","type":"journal_article","oa":1,"language":[{"iso":"eng"}],"issue":"2","citation":{"mla":"Hubert, Colin, et al. “Attractive Dipolar Coupling between Stacked Exciton Fluids.” <i>Physical Review X</i>, vol. 9, no. 2, 021026, American Physical Society, 2019, doi:<a href=\"https://doi.org/10.1103/PhysRevX.9.021026\">10.1103/PhysRevX.9.021026</a>.","apa":"Hubert, C., Baruchi, Y., Mazuz-Harpaz, Y., Cohen, K., Biermann, K., Lemeshko, M., … Santos, P.

Unlike Coulomb or contactlike interactions found in many atomic, molecular, and condensed-matter systems, this interaction is long-ranged and highly anisotropic, as it changes from repulsive to attractive depending on the relative positions and orientation of the dipoles. Because of this unique property, many exotic, symmetry-breaking collective states have been recently predicted for cold dipolar gases, but only a few have been experimentally detected and only in dilute atomic dipolar Bose-Einstein condensates. Here, we report on the first observation of attractive dipolar coupling between excitonic dipoles using a new design of stacked semiconductor bilayers. We show that the presence of a dipolar exciton fluid in one bilayer modifies the spatial distribution and increases the binding energy of excitonic dipoles in a vertically remote layer. The binding energy changes are explained using a many-body polaron model describing the deformation of the exciton cloud due to its interaction with a remote dipolar exciton. The surprising nonmonotonic dependence on the cloud density indicates the important role of dipolar correlations, which is unique to dense, strongly interacting dipolar solid-state systems. Our concept provides a route for the realization of dipolar lattices with strong anisotropic interactions in semiconductor systems, which open the way for the observation of theoretically predicted new and exotic collective phases, as well as for engineering and sensing their collective excitations.","lang":"eng"}],"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","image":"/images/cc_by.png","short":"CC BY (4.0)"},"intvolume":"         9","publication_status":"published","publication_identifier":{"eissn":["2160-3308"]},"file_date_updated":"2020-07-14T12:47:40Z","author":[{"first_name":"Colin","full_name":"Hubert, Colin","last_name":"Hubert"},{"full_name":"Baruchi, Yifat","last_name":"Baruchi","first_name":"Yifat"},{"first_name":"Yotam","last_name":"Mazuz-Harpaz","full_name":"Mazuz-Harpaz, Yotam"},{"first_name":"Kobi","full_name":"Cohen, Kobi","last_name":"Cohen"},{"full_name":"Biermann, Klaus","last_name":"Biermann","first_name":"Klaus"},{"orcid":"0000-0002-6990-7802","first_name":"Mikhail","full_name":"Lemeshko, Mikhail","id":"37CB05FA-F248-11E8-B48F-1D18A9856A87","last_name":"Lemeshko"},{"first_name":"Ken","last_name":"West","full_name":"West, Ken"},{"first_name":"Loren","full_name":"Pfeiffer, Loren","last_name":"Pfeiffer"},{"full_name":"Rapaport, Ronen","last_name":"Rapaport","first_name":"Ronen"},{"first_name":"Paulo","full_name":"Santos, Paulo","last_name":"Santos"}],"scopus_import":"1","day":"08","title":"Attractive dipolar coupling between stacked exciton fluids","oa_version":"Published Version","volume":9,"article_type":"original","date_created":"2019-08-11T21:59:20Z"},{"arxiv":1,"month":"09","article_number":"035005 ","department":[{"_id":"MiLe"}],"language":[{"iso":"eng"}],"oa":1,"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","citation":{"apa":"Koch, C.

Molecular angular momentum is naturally quantized, time evolution is governed by a well-known Hamiltonian with only a few accurately known parameters, and transitions between rotational levels can be driven by external fields from various parts of the electromagnetic spectrum. Control over the rotational motion can be exerted in one-, two-, and many-body scenarios, thereby allowing one to probe Anderson localization, target stereoselectivity of bimolecular reactions, or encode quantum information to name just a few examples. The corresponding approaches to quantum control are pursued within separate, and typically disjoint, subfields of physics, including ultrafast science, cold collisions, ultracold gases, quantum information science, and condensed-matter physics. It is the purpose of this review to present the various control phenomena, which all rely on the same underlying physics, within a unified framework. To this end, recall the Hamiltonian for free rotations, assuming the rigid rotor approximation to be valid, and summarize the different ways for a rotor to interact with external electromagnetic fields. These interactions can be exploited for control—from achieving alignment, orientation, or laser cooling in a one-body framework, steering bimolecular collisions, or realizing a quantum computer or quantum simulator in the many-body setting."}],"intvolume":"        91","publication_identifier":{"eissn":["1539-0756"],"issn":["0034-6861"]},"publication_status":"published","external_id":{"isi":["000486661700001"],"arxiv":["1810.11338"]},"isi":1,"year":"2019","publication":"Reviews of Modern Physics","status":"public","project":[{"call_identifier":"FWF","name":"Quantum rotations in the presence of a many-body environment","grant_number":"P29902","_id":"26031614-B435-11E9-9278-68D0E5697425"}],"date_published":"2019-09-18T00:00:00Z","publisher":"American Physical Society","article_processing_charge":"No","doi":"10.1103/revmodphys.91.035005","type":"journal_article","_id":"7396","date_updated":"2024-02-28T13:15:33Z","quality_controlled":"1","main_file_link":[{"url":"https://arxiv.org/abs/1810.11338","open_access":"1"}]},{"month":"01","file":[{"file_name":"2019_MolecularPhysics_Li.pdf","access_level":"open_access","content_type":"application/pdf","relation":"main_file","checksum":"178964744b636a6f036372f4f090a657","file_size":1309966,"date_created":"2019-01-29T08:32:57Z","creator":"dernst","date_updated":"2020-07-14T12:47:13Z","file_id":"5896"}],"department":[{"_id":"MiLe"}],"language":[{"iso":"eng"}],"oa":1,"user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","citation":{"apa":"Li, X., Bighin, G., Yakaboylu, E., &#38; Lemeshko, M.

Until now, the timescales of electron-to-lattice angular momentum transfer remain unclear, since modeling this process on a microscopic level requires the addition of an infinite amount of quantum angular momenta. We show that this problem can be solved by reformulating it in terms of the recently discovered angulon quasiparticles, which results in a rotationally invariant quantum many-body theory.

The emerging flux tube acts as a statistical gauge field after a certain critical coupling. This critical coupling corresponds to the intersection point between the quasiparticle state and the phonon wing, where the angular momentum is transferred from the impurity to the bath.

Crucially, the single deformation parameter, q, contains all the information about the many-particle interactions in the system. We exemplify our approach by considering a quantum rotor interacting with a bath of bosons, and demonstrate that extracting the value of q from closed-form solutions in the perturbative regime allows one to predict the behavior of the system for arbitrary values of the impurity-bath coupling strength, in good agreement with nonperturbative calculations. Furthermore, the value of the deformation parameter allows one to predict at which coupling strengths rotor-bath interactions result in a formation of a stable quasiparticle. The approach based on quantum groups does not only allow for a drastic simplification of impurity problems, but also provides valuable insights into hidden symmetries of interacting many-particle systems."}],"publication_identifier":{"issn":["00319007"]},"publication_status":"published"},{"quality_controlled":"1","main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/1803.07990"}],"type":"journal_article","date_updated":"2024-02-28T13:15:09Z","_id":"6339","publisher":"American Physical Society","doi":"10.1103/physrevlett.121.165301","article_processing_charge":"No","date_published":"2018-10-16T00:00:00Z","project":[{"_id":"26031614-B435-11E9-9278-68D0E5697425","call_identifier":"FWF","grant_number":"P29902","name":"Quantum rotations in the presence of a many-body environment"}],"publication":"Physical Review Letters","status":"public","external_id":{"isi":["000447468400008"],"arxiv":["1803.07990"]},"related_material":{"link":[{"relation":"press_release","description":"News on IST Homepage","url":"https://ist.ac.at/en/news/description-of-rotating-molecules-made-easy/"}]},"isi":1,"year":"2018","publication_status":"published","intvolume":"       121","abstract":[{"text":"We introduce a diagrammatic Monte Carlo approach to angular momentum properties of quantum many-particle systems possessing a macroscopic number of degrees of freedom.

The treatment is based on the diagrammatic expansion that merges the usual Feynman diagrams with the angular momentum diagrams known from atomic and nuclear structure theory, thereby incorporating the non-Abelian algebra inherent to quantum rotations. Our approach works at arbitrary coupling, is free of systematic errors and of finite size effects, and naturally provides access to the impurity Green function. We exemplify the technique by obtaining an all-coupling solution of the angulon model, however, the method is quite general and can be applied to a broad variety of quantum impurities possessing angular momentum degrees of freedom.

With increasing fluence, however, the revivals disappear -- instead, rotational dynamics as rapid as for an isolated molecule is observed during the first few picoseconds. Classical calculations trace this phenomenon to transient decoupling of the molecule from its He shell.
