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.

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"}],"ec_funded":1,"date_created":"2020-12-21T09:44:30Z","month":"12","oa":1},{"arxiv":1,"publication_identifier":{"issn":["0031-9007"],"eissn":["1079-7114"]},"status":"public","user_id":"ba8df636-2132-11f1-aed0-ed93e2281fdd","date_published":"2020-07-03T00:00:00Z","article_number":"013001","ec_funded":1,"abstract":[{"text":"Alignment of OCS, CS2, and I2 molecules embedded in helium nanodroplets is measured as a function\r\nof time following rotational excitation by a nonresonant, comparatively weak ps laser pulse.

At the microscopic level, this effect governs the transfer between electron spin and orbital angular momentum, and lattice degrees of freedom, understanding which is key for molecular magnets, nano-magneto-mechanics, spintronics, and ultrafast magnetism. 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. In particular, we demonstrate that nonperturbative effects take place even if the electron-phonon coupling is weak and give rise to angular momentum transfer on femtosecond timescales.","lang":"eng"}],"oa":1,"publication":"Physical Review B","date_created":"2019-03-10T22:59:20Z","month":"02","doi":"10.1103/PhysRevB.99.064428","oa_version":"Preprint","citation":{"ista":"Mentink JH, Katsnelson M, Lemeshko M. 2019.

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."}],"language":[{"iso":"eng"}],"oa_version":"Published Version","doi":"10.1103/PhysRevX.9.021026","citation":{"apa":"Hubert, C., Baruchi, Y., Mazuz-Harpaz, Y., Cohen, K., Biermann, K., Lemeshko, M., … Santos, P.

We consider spinless fermions with no fermion-fermion interactions. The fermion-impurity and impurity-impurity interactions are modeled with Dirac delta functions. First, we study the case where impurity and fermion have equal masses, and the impurity-impurity two-body interaction is identical to the fermion-impurity interaction, such that the system is solvable with the Bethe ansatz. For attractive interactions, we find that the energy of the impurity-impurity subsystem is below the energy of the bound state that exists without the Fermi gas. We interpret this as a manifestation of attractive boson-boson interactions induced by the fermionic medium, and refer to the impurity-impurity subsystem as an in-medium bound state. For repulsive interactions, we find no in-medium bound states. Second, we construct an effective model to describe these interactions, and compare its predictions to the exact solution. We use this effective model to study nonintegrable systems with unequal masses and/or potentials. We discuss parameter regimes for which impurity-impurity attraction induced by the Fermi gas can lead to the formation of in-medium bound states made of bosons that repel each other in the absence of the Fermi gas."}],"ec_funded":1,"scopus_import":"1","language":[{"iso":"eng"}],"oa_version":"Published Version","doi":"10.1103/physrevresearch.1.033177","citation":{"mla":"Huber, D., et al. “In-Medium Bound States of Two Bosonic Impurities in a One-Dimensional Fermi Gas.” <i>Physical Review Research</i>, vol. 1, no. 3, 033177, American Physical Society, 2019, doi:<a href=\"https://doi.org/10.1103/physrevresearch.1.033177\">10.1103/physrevresearch.1.033177</a>.","ista":"Huber D, Hammer H-W, Volosniev A. 2019.

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.","lang":"eng"}],"oa":1,"publication":"Reviews of Modern Physics","month":"09","date_created":"2020-01-29T16:04:19Z","project":[{"call_identifier":"FWF","grant_number":"P29902","name":"Quantum rotations in the presence of a many-body environment","_id":"26031614-B435-11E9-9278-68D0E5697425"}],"external_id":{"arxiv":["1810.11338"],"isi":["000486661700001"]},"article_type":"original","day":"18","volume":91,"year":"2019","isi":1,"type":"journal_article","publication_status":"published","issue":"3","date_updated":"2025-04-15T07:59:29Z","department":[{"_id":"MiLe"}],"title":"Quantum control of molecular rotation","article_processing_charge":"No","quality_controlled":"1","main_file_link":[{"url":"https://arxiv.org/abs/1810.11338","open_access":"1"}],"author":[{"last_name":"Koch","first_name":"Christiane P.","full_name":"Koch, Christiane P."},{"full_name":"Lemeshko, Mikhail","first_name":"Mikhail","id":"37CB05FA-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-6990-7802","last_name":"Lemeshko"},{"last_name":"Sugny","full_name":"Sugny, Dominique","first_name":"Dominique"}],"publisher":"American Physical Society"},{"ddc":["530"],"publisher":"Taylor and Francis","quality_controlled":"1","author":[{"first_name":"Xiang","full_name":"Li, Xiang","last_name":"Li","id":"4B7E523C-F248-11E8-B48F-1D18A9856A87"},{"id":"4CA96FD4-F248-11E8-B48F-1D18A9856A87","last_name":"Bighin","orcid":"0000-0001-8823-9777","full_name":"Bighin, Giacomo","first_name":"Giacomo"},{"id":"38CB71F6-F248-11E8-B48F-1D18A9856A87","last_name":"Yakaboylu","orcid":"0000-0001-5973-0874","full_name":"Yakaboylu, Enderalp","first_name":"Enderalp"},{"first_name":"Mikhail","full_name":"Lemeshko, Mikhail","orcid":"0000-0002-6990-7802","last_name":"Lemeshko","id":"37CB05FA-F248-11E8-B48F-1D18A9856A87"}],"has_accepted_license":"1","date_updated":"2026-04-08T07:26:09Z","department":[{"_id":"MiLe"}],"title":"Variational approaches to quantum impurities: from the Fröhlich polaron to the angulon","article_processing_charge":"No","file":[{"file_size":1309966,"file_id":"5896","date_created":"2019-01-29T08:32:57Z","relation":"main_file","file_name":"2019_MolecularPhysics_Li.pdf","creator":"dernst","content_type":"application/pdf","date_updated":"2020-07-14T12:47:13Z","access_level":"open_access","checksum":"178964744b636a6f036372f4f090a657"}],"type":"journal_article","publication_status":"published","isi":1,"day":"18","year":"2019","project":[{"_id":"26031614-B435-11E9-9278-68D0E5697425","name":"Quantum rotations in the presence of a many-body environment","call_identifier":"FWF","grant_number":"P29902"},{"call_identifier":"FP7","grant_number":"291734","_id":"25681D80-B435-11E9-9278-68D0E5697425","name":"International IST Postdoc Fellowship Programme"}],"external_id":{"isi":["000474641400008"]},"file_date_updated":"2020-07-14T12:47:13Z","oa":1,"month":"01","publication":"Molecular Physics","date_created":"2019-01-27T22:59:10Z","ec_funded":1,"scopus_import":"1","abstract":[{"lang":"eng","text":"Problems involving quantum impurities, in which one or a few particles are interacting with a macroscopic environment, represent a pervasive paradigm, spanning across atomic, molecular, and condensed-matter physics.

In particular, we show that, if the symmetry of a free quantum particle corresponds to a Lie group G, in the presence of a many-body environment this particle can be described by a deformed group, Gq. 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."}],"scopus_import":"1","ec_funded":1,"article_type":"original","external_id":{"arxiv":["1809.00222"],"isi":["000454178600009"]},"project":[{"name":"International IST Postdoc Fellowship Programme","_id":"25681D80-B435-11E9-9278-68D0E5697425","call_identifier":"FP7","grant_number":"291734"},{"_id":"26031614-B435-11E9-9278-68D0E5697425","name":"Quantum rotations in the presence of a many-body environment","grant_number":"P29902","call_identifier":"FWF"}],"isi":1,"year":"2018","volume":121,"day":"17","article_processing_charge":"No","title":"Quantum groups as hidden symmetries of quantum impurities","department":[{"_id":"MiLe"}],"date_updated":"2025-04-15T06:50:24Z","issue":"25","publication_status":"published","type":"journal_article","publisher":"American Physical Society","author":[{"first_name":"Enderalp","full_name":"Yakaboylu, Enderalp","last_name":"Yakaboylu","orcid":"0000-0001-5973-0874","id":"38CB71F6-F248-11E8-B48F-1D18A9856A87"},{"full_name":"Shkolnikov, Mikhail","first_name":"Mikhail","id":"35084A62-F248-11E8-B48F-1D18A9856A87","last_name":"Shkolnikov","orcid":"0000-0002-4310-178X"},{"orcid":"0000-0002-6990-7802","last_name":"Lemeshko","id":"37CB05FA-F248-11E8-B48F-1D18A9856A87","first_name":"Mikhail","full_name":"Lemeshko, Mikhail"}],"quality_controlled":"1","main_file_link":[{"url":"https://arxiv.org/abs/1809.00222","open_access":"1"}]},{"date_published":"2018-12-12T00:00:00Z","user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","status":"public","article_number":"224506","publication_identifier":{"eissn":["2469-9969"],"issn":["2469-9950"]},"arxiv":1,"_id":"5983","intvolume":"        98","oa_version":"Preprint","doi":"10.1103/physrevb.98.224506","citation":{"short":"E.

In this work, we focus on hyperfine states of lithiumlike heavy-Z isotopes and quantify how much quantum interference changes the observed transition frequencies. The process of photon excitation and subsequent photon decay for the transition 2s→2p→2s is implemented with fully relativistic and full-multipole frameworks, which are relevant for such relativistic atomic systems. We consider the isotopes Pb79+207 and Bi80+209 due to experimental interest, as well as other examples of isotopes with lower Z, namely Pr56+141 and Ho64+165. We conclude that quantum interference can induce shifts up to 11% of the linewidth in the measurable resonances of the considered isotopes, if interference between resonances is neglected. The inclusion of relativity decreases the cross section by 35%, mainly due to the complete retardation form of the electric dipole multipole. However, the contribution of the next higher multipoles (e.g., magnetic quadrupole) to the cross section is negligible. This makes the contribution of relativity and higher-order multipoles to the quantum interference induced shifts a minor effect, even for heavy-Z elements.","lang":"eng"}],"ec_funded":1,"language":[{"iso":"eng"}],"_id":"427","intvolume":"        97","oa_version":"Preprint","doi":"10.1103/PhysRevA.97.022510","citation":{"ista":"Amaro P, Loureiro U, Safari L, Fratini F, Indelicato P, Stöhlker T, Santos J. 2018.
