Already for a few particles we find a ground-state level crossing between sectors with different fermion parities. We interpret this crossing as a few-body precursor of a quantum phase transition, which occurs when the impurity \"breaks\" a Cooper pair.

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.","lang":"eng"}],"file_date_updated":"2023-09-05T08:45:49Z","doi":"10.1038/s42005-023-01281-2","oa":1,"article_type":"original","tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png"},"oa_version":"Published Version","date_created":"2023-08-28T12:36:49Z","title":"Emergence of a Bose polaron in a small ring threaded by the Aharonov-Bohm flux","citation":{"chicago":"Brauneis, Fabian, Areg Ghazaryan, Hans-Werner Hammer, and Artem Volosniev. “Emergence of a Bose Polaron in a Small Ring Threaded by the Aharonov-Bohm Flux.” Communications Physics.

Comparison to alignment dynamics calculated from the time-dependent rotational Schrödinger equation shows that the deviation is due to the alignment dependent interaction between the dimer and the droplet surface. This interaction confines the dimer to the tangential plane of the droplet surface at the point where it resides and is the reason that the observed alignment dynamics is also well described by a 2D quantum rotor model."}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","doi":"10.1103/PhysRevLett.131.053201","oa":1,"article_type":"original","oa_version":"Preprint","ec_funded":1,"main_file_link":[{"open_access":"1","url":"https://doi.org/10.48550/arXiv.2308.15247"}],"date_created":"2023-08-27T22:01:16Z","title":"Nonadiabatic laser-induced alignment dynamics of molecules on a surface","citation":{"chicago":"Kranabetter, Lorenz, Henrik H.

First, we derive mean-field solutions to the problem on a finite ring for the two asymptotic cases: (i) all bosons are bound to the impurity and (ii) all bosons are in a scattering state. Moreover, we derive the critical line that separates these regimes in the parameter space. In the thermodynamic limit, this critical line determines the maximum number of bosons that can be bound by the impurity potential, forming an artificial atom. Second, we validate the mean-field results using the flow equation approach and the multi-layer multi-configuration time-dependent Hartree method for atomic mixtures. While beyond-mean-field effects destroy long-range order in the Bose gas, the critical boson number is unaffected. Our findings are important for understanding such artificial atoms in low-density Bose gases with static and mobile impurities.","lang":"eng"}],"user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","file_date_updated":"2022-07-18T06:33:13Z","doi":"10.1088/1367-2630/ac78d8","project":[{"call_identifier":"H2020","name":"ISTplus - Postdoctoral Fellowships","grant_number":"754411","_id":"260C2330-B435-11E9-9278-68D0E5697425"},{"_id":"2688CF98-B435-11E9-9278-68D0E5697425","grant_number":"801770","name":"Angulon: physics and applications of a new quasiparticle","call_identifier":"H2020"}],"file":[{"checksum":"dc67b60f2e50e9ef2bd820ca0d7333d2","file_id":"11594","creator":"dernst","access_level":"open_access","file_name":"2022_NewJournalPhysics_Brauneis.pdf","relation":"main_file","file_size":3415721,"date_created":"2022-07-18T06:33:13Z","success":1,"date_updated":"2022-07-18T06:33:13Z","content_type":"application/pdf"}],"oa":1,"article_type":"original","intvolume":" 24","publication":"New Journal of Physics","issue":"6","year":"2022","status":"public","department":[{"_id":"MiLe"}],"publication_status":"published"},{"author":[{"first_name":"Giacomo","orcid":"0000-0001-8823-9777","last_name":"Bighin","id":"4CA96FD4-F248-11E8-B48F-1D18A9856A87","full_name":"Bighin, Giacomo"},{"orcid":"0000-0001-6110-2359","first_name":"Alberto","full_name":"Cappellaro, Alberto","id":"9d13b3cb-30a2-11eb-80dc-f772505e8660","last_name":"Cappellaro"},{"full_name":"Salasnich, L.","last_name":"Salasnich","first_name":"L."}],"publisher":"American Physical Society","volume":105,"scopus_import":"1","type":"journal_article","article_processing_charge":"No","acknowledgement":"The authors gratefully acknowledge stimulating discussions with T.

Rev. A 104 L061303). This calls for theoretical approaches that go beyond explaining renormalized values of molecular spectroscopic constants, which suffices when only the lowest few rotational states are involved. As the first step in this direction, here we present a basic quantum mechanical model describing highly excited rotational states of molecules in superfluid helium nanodroplets. We show that a linear molecule immersed in a superfluid can be seen as an effective symmetric top, similar to the rotational structure of radicals, such as OH or NO, but with the angular momentum of the superfluid playing the role of the electronic angular momentum in free molecules. The simple theory sheds light onto what happens when the rotational angular momentum of the molecule increases beyond the lowest excited states accessible by infrared spectroscopy. In addition, the model allows to estimate the effective rotational and centrifugal distortion constants for a broad range of species and to explain the crossover between light and heavy molecules in superfluid 4He in terms of the many-body wavefunction structure. Some of the above mentioned insights can be acquired by analyzing a simple 2 × 2 matrix."}],"date_created":"2022-08-28T22:02:01Z","title":"A simple model for high rotational excitations of molecules in a superfluid","citation":{"ama":"Cherepanov I, Bighin G, Schouder CA, Chatterley AS, Stapelfeldt H, Lemeshko M.
