Here, we propose a coherent state ansatz in the co-rotating frame, which provides a comprehensive theoretical description of angulons. We reveal the quasiparticle properties, such as energies, quasiparticle weights, and spectral functions, and show that our ansatz yields a persistent decrease in the impurity’s rotational constant due to many-body dressing, which is consistent with experimental observations. From our study, a picture of the angulon emerges as an effective spin interacting with a magnetic field that is self-consistently generated by the molecule’s rotation. Moreover, we discuss rotational spectroscopy, which focuses on the response of rotating molecules to a laser perturbation in the linear response regime. Importantly, we take into account initial-state interactions that have been neglected in prior studies and reveal their impact on the excitation spectrum. To examine the angulon instability regime, we use a single-excitation ansatz and obtain results consistent with experiments, in which a broadening of spectral lines is observed while phonon wings remain highly suppressed due to initial-state interactions.","lang":"eng"}],"ec_funded":1,"volume":158,"issue":"13","language":[{"iso":"eng"}],"file":[{"file_size":7388057,"date_updated":"2023-04-17T07:28:38Z","creator":"dernst","file_name":"2023_JourChemicalPhysics_Zeng.pdf","date_created":"2023-04-17T07:28:38Z","content_type":"application/pdf","relation":"main_file","access_level":"open_access","success":1,"file_id":"12841","checksum":"8d801babea4df48e08895c76571bb19e"}],"publication_status":"published","publication_identifier":{"eissn":["1089-7690"]},"status":"public","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)"},"article_type":"original","type":"journal_article","_id":"12831","file_date_updated":"2023-04-17T07:28:38Z","department":[{"_id":"MiLe"}],"ddc":["530"],"date_updated":"2023-08-01T14:08:47Z","oa":1,"publisher":"American Institute of Physics","quality_controlled":"1","acknowledgement":"We thank Ignacio Cirac, Christian Schmauder, and Henrik Stapelfeldt for their valuable discussions.

It is known, however, that the geometry and topology of space can have significant effects on quantum statistics for particles moving on it. Here, we have undertaken the first step toward realizing the emerging fractional statistics for particles restricted to move on the sphere instead of on the plane. We show that such a model arises naturally in the context of quantum impurity problems. In particular, we demonstrate a setup in which the lowest-energy spectrum of two linear bosonic or fermionic molecules immersed in a quantum many-particle environment can coincide with the anyonic spectrum on the sphere. This paves the way toward the experimental realization of anyons on the sphere using molecular impurities. Furthermore, since a change in the alignment of the molecules corresponds to the exchange of the particles on the sphere, such a realization reveals a novel type of exclusion principle for molecular impurities, which could also be of use as a powerful technique to measure the statistics parameter. Finally, our approach opens up a simple numerical route to investigate the spectra of many anyons on the sphere. Accordingly, we present the spectrum of two anyons on the sphere in the presence of a Dirac monopole field.","lang":"eng"}],"oa_version":"Preprint","main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/2009.05948"}],"scopus_import":"1","intvolume":" 126","month":"01","publication_status":"published","publication_identifier":{"issn":["00319007"],"eissn":["10797114"]},"language":[{"iso":"eng"}],"ec_funded":1,"related_material":{"record":[{"relation":"dissertation_contains","status":"public","id":"12390"}],"link":[{"relation":"press_release","url":"https://ist.ac.at/en/news/dancing-molecules-and-two-dimensional-particles/","description":"News on IST Homepage"}]},"volume":126,"issue":"1","_id":"9005","article_type":"original","type":"journal_article","status":"public","date_updated":"2023-08-07T13:32:10Z","department":[{"_id":"MiLe"},{"_id":"RoSe"}],"acknowledgement":"We are grateful to A.

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.

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."}],"month":"10","intvolume":" 102","scopus_import":"1","main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/1912.07890"}],"language":[{"iso":"eng"}],"publication_identifier":{"issn":["2469-9950"],"eissn":["2469-9969"]},"publication_status":"published","volume":102,"issue":"14","ec_funded":1,"_id":"8769","status":"public","type":"journal_article","article_type":"original","date_updated":"2023-09-05T12:12:30Z","department":[{"_id":"MiLe"},{"_id":"RoSe"}],"acknowledgement":"We are grateful to 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."}],"oa_version":"Preprint","ec_funded":1,"volume":152,"related_material":{"record":[{"id":"8958","status":"public","relation":"dissertation_contains"}]},"issue":"16","publication_status":"published","publication_identifier":{"issn":["0021-9606"],"eissn":["1089-7690"]},"language":[{"iso":"eng"}],"project":[{"name":"Quantum rotations in the presence of a many-body environment","grant_number":"P29902","call_identifier":"FWF","_id":"26031614-B435-11E9-9278-68D0E5697425"},{"grant_number":"801770","name":"Angulon: physics and applications of a new quasiparticle","call_identifier":"H2020","_id":"2688CF98-B435-11E9-9278-68D0E5697425"},{"call_identifier":"FWF","_id":"26986C82-B435-11E9-9278-68D0E5697425","grant_number":"M02641","name":"A path-integral approach to composite impurities"},{"_id":"25C6DC12-B435-11E9-9278-68D0E5697425","call_identifier":"H2020","name":"Analysis of quantum many-body systems","grant_number":"694227"}],"article_number":"164302","external_id":{"isi":["000530448300001"],"arxiv":["1912.02658"]},"article_processing_charge":"No","author":[{"last_name":"Li","full_name":"Li, Xiang","first_name":"Xiang","id":"4B7E523C-F248-11E8-B48F-1D18A9856A87"},{"id":"38CB71F6-F248-11E8-B48F-1D18A9856A87","first_name":"Enderalp","orcid":"0000-0001-5973-0874","full_name":"Yakaboylu, Enderalp","last_name":"Yakaboylu"},{"last_name":"Bighin","orcid":"0000-0001-8823-9777","full_name":"Bighin, Giacomo","first_name":"Giacomo","id":"4CA96FD4-F248-11E8-B48F-1D18A9856A87"},{"first_name":"Richard","last_name":"Schmidt","full_name":"Schmidt, Richard"},{"orcid":"0000-0002-6990-7802","full_name":"Lemeshko, Mikhail","last_name":"Lemeshko","first_name":"Mikhail","id":"37CB05FA-F248-11E8-B48F-1D18A9856A87"},{"id":"4DA65CD0-F248-11E8-B48F-1D18A9856A87","first_name":"Andreas","full_name":"Deuchert, Andreas","orcid":"0000-0003-3146-6746","last_name":"Deuchert"}],"title":"Intermolecular forces and correlations mediated by a phonon bath","citation":{"ista":"Li X, Yakaboylu E, Bighin G, Schmidt R, Lemeshko M, Deuchert A. 2020.

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.

We reveal how the coupling between linear and angular momenta affects stable quasiparticle states, and demonstrate that internal rotation leads to an enhanced self-localization in the translational degrees of freedom.","lang":"eng"}],"oa_version":"Preprint","ec_funded":1,"volume":98,"issue":"22","publication_status":"published","publication_identifier":{"issn":["2469-9950"],"eissn":["2469-9969"]},"language":[{"iso":"eng"}],"project":[{"name":"International IST Postdoc Fellowship Programme","grant_number":"291734","_id":"25681D80-B435-11E9-9278-68D0E5697425","call_identifier":"FP7"},{"call_identifier":"H2020","_id":"25C6DC12-B435-11E9-9278-68D0E5697425","name":"Analysis of quantum many-body systems","grant_number":"694227"}],"article_number":"224506","external_id":{"isi":["000452992700008"],"arxiv":["1809.01204"]},"article_processing_charge":"No","author":[{"id":"38CB71F6-F248-11E8-B48F-1D18A9856A87","first_name":"Enderalp","last_name":"Yakaboylu","orcid":"0000-0001-5973-0874","full_name":"Yakaboylu, Enderalp"},{"first_name":"Bikashkali","id":"456187FC-F248-11E8-B48F-1D18A9856A87","last_name":"Midya","full_name":"Midya, Bikashkali"},{"first_name":"Andreas","id":"4DA65CD0-F248-11E8-B48F-1D18A9856A87","last_name":"Deuchert","orcid":"0000-0003-3146-6746","full_name":"Deuchert, Andreas"},{"first_name":"Nikolai K","id":"4BC40BEC-F248-11E8-B48F-1D18A9856A87","last_name":"Leopold","full_name":"Leopold, Nikolai K","orcid":"0000-0002-0495-6822"},{"first_name":"Mikhail","id":"37CB05FA-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-6990-7802","full_name":"Lemeshko, Mikhail","last_name":"Lemeshko"}],"title":"Theory of the rotating polaron: Spectrum and self-localization","citation":{"short":"E.

Owing to advances in laser technology, electric fields comparable to those electrons experience in atoms are readily generated and open opportunities to dynamically investigate the process of electron tunneling through the potential barrier formed by the superposition of both laser and atomic fields. Attosecond-time and angstrom-space resolution of the strong laser-field technique allow to address fundamental questions related to tunneling, which are still open and debated: Which time is spent under the barrier and what momentum is picked up by the particle in the meantime? In this combined experimental and theoretical study we demonstrate that for strong-field ionization the leading quantum mechanical Wigner treatment for the time resolved description of tunneling is valid. We achieve a high sensitivity on the tunneling barrier and unambiguously isolate its effects by performing a differential study of two systems with almost identical tunneling geometry. Moreover, working with a low frequency laser, we essentially limit the non-adiabaticity of the process as a major source of uncertainty. The agreement between experiment and theory implies two substantial corrections with respect to the widely employed quasiclassical treatment: In addition to a non-vanishing longitudinal momentum along the laser field-direction we provide clear evidence for a non-zero tunneling time delay. This addresses also the fundamental question how the transition occurs from the tunnel barrier to free space classical evolution of the ejected electron.","lang":"eng"}],"intvolume":" 999","month":"07","alternative_title":["Journal of Physics: Conference Series"],"scopus_import":1,"language":[{"iso":"eng"}],"file":[{"file_id":"5871","checksum":"6e70b525a84f6d5fb175c48e9f5cb59a","content_type":"application/pdf","relation":"main_file","access_level":"open_access","file_name":"2017_Physics_Camus.pdf","date_created":"2019-01-22T08:34:10Z","file_size":949321,"date_updated":"2020-07-14T12:46:00Z","creator":"dernst"}],"publication_status":"published","publication_identifier":{"issn":["17426588"]},"volume":999,"related_material":{"record":[{"relation":"later_version","status":"public","id":"6013"}]},"issue":"1","_id":"313","status":"public","conference":{"end_date":"2017-08-21","location":"Kazan, Russian Federation","start_date":"2017-08-17","name":"Annual International Laser Physics Workshop LPHYS"},"tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)"},"type":"conference","ddc":["530"],"date_updated":"2023-02-23T12:36:07Z","file_date_updated":"2020-07-14T12:46:00Z","department":[{"_id":"MiLe"}],"oa":1,"publisher":"American Physical Society","quality_controlled":"1","day":"14","year":"2017","has_accepted_license":"1","date_created":"2018-12-11T11:45:46Z","date_published":"2017-07-14T00:00:00Z","doi":"10.1088/1742-6596/999/1/012004","article_number":"012004","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","citation":{"chicago":"Camus, Nicolas, Enderalp Yakaboylu, Lutz Fechner, Michael Klaiber, Martin Laux, Yonghao Mi, Karen Hatsagortsyan, Thomas Pfeifer, Cristoph Keitel, and Robert Moshammer. “Experimental Evidence for Wigner’s Tunneling Time,” Vol. 999.

Although without high-order corrections our theory coincides with the known analytical R-matrix (ARM) theory, we propose a simplified procedure for the matrix element derivation. Rather than matching the eikonal Coulomb-Volkov wave function with the bound state as in the ARM theory to remove the Coulomb singularity, we calculate the matrix element via the saddle-point integration method by time as well as by coordinate, and in this way avoiding the Coulomb singularity.

Rev. Lett. 118, 095301 (2017)). Here we demonstrate that in the experimentally realized regime the angulon can be seen as a point charge on a 2-sphere interacting with a gauge field of a non-abelian magnetic monopole. Unlike in several other settings, the gauge fields of the angulon problem emerge in the real coordinate space, as opposed to the momentum space or some effective parameter space. Furthermore, we find a topological transition associated with making the monopole abelian, which takes place in the vicinity of the previously reported angulon instabilities. These results pave the way for studying topological phenomena in experiments on molecules trapped in superfluid helium nanodroplets, as well as on other realizations of orbital impurity problems.","lang":"eng"}],"month":"12","intvolume":" 119","scopus_import":"1","main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/1705.05162"}],"date_updated":"2023-10-10T13:31:54Z","department":[{"_id":"MiLe"},{"_id":"RoSe"}],"_id":"997","status":"public","type":"journal_article","article_type":"original"}]
