Such a system corresponds to a “rotating polaron,” which can be used to model, e.g., a rotating molecule immersed in an ultracold Bose gas or superfluid helium. We derive the Hamiltonian of the rotating polaron and study its spectrum in the weak- and strong-coupling regimes using a combination of variational, diagrammatic, and mean-field approaches. 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"}],"main_file_link":[{"url":"https://arxiv.org/abs/1809.01204","open_access":"1"}],"department":[{"_id":"MiLe"},{"_id":"RoSe"}],"issue":"22","date_published":"2018-12-12T00:00:00Z","publication_status":"published","year":"2018","volume":98,"intvolume":"        98","project":[{"_id":"25681D80-B435-11E9-9278-68D0E5697425","name":"International IST Postdoc Fellowship Programme","grant_number":"291734","call_identifier":"FP7"},{"call_identifier":"H2020","grant_number":"694227","name":"Analysis of quantum many-body systems","_id":"25C6DC12-B435-11E9-9278-68D0E5697425"}],"isi":1,"publication_identifier":{"eissn":["2469-9969"],"issn":["2469-9950"]},"external_id":{"arxiv":["1809.01204"],"isi":["000452992700008"]},"publication":"Physical Review B","author":[{"orcid":"0000-0001-5973-0874","last_name":"Yakaboylu","first_name":"Enderalp","id":"38CB71F6-F248-11E8-B48F-1D18A9856A87","full_name":"Yakaboylu, Enderalp"},{"full_name":"Midya, Bikashkali","id":"456187FC-F248-11E8-B48F-1D18A9856A87","first_name":"Bikashkali","last_name":"Midya"},{"first_name":"Andreas","last_name":"Deuchert","id":"4DA65CD0-F248-11E8-B48F-1D18A9856A87","full_name":"Deuchert, Andreas","orcid":"0000-0003-3146-6746"},{"last_name":"Leopold","first_name":"Nikolai K","full_name":"Leopold, Nikolai K","id":"4BC40BEC-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-0495-6822"},{"last_name":"Lemeshko","first_name":"Mikhail","id":"37CB05FA-F248-11E8-B48F-1D18A9856A87","full_name":"Lemeshko, Mikhail","orcid":"0000-0002-6990-7802"}],"doi":"10.1103/physrevb.98.224506","_id":"5983","article_number":"224506","language":[{"iso":"eng"}],"citation":{"ieee":"E.
