Here we demonstrate that very strong, \"anomalous\" screening can take place in the presence of a neutral, weakly polarizable environment, due to an exchange of orbital angular momentum between the impurity and the bath. Furthermore, we show that it is possible to generalize all phenomena related to isolated impurities in an external field to the case when a many-body environment is present, by casting the problem in terms of the angulon quasiparticle. As a result, the relevant observables such as the effective Rabi frequency, geometric phase, and impurity spatial alignment are straightforward to evaluate in terms of a single parameter: the angular-momentum-dependent screening factor."}],"main_file_link":[{"url":"https://arxiv.org/abs/1612.02820","open_access":"1"}],"department":[{"_id":"MiLe"}],"issue":"8","publication_status":"published","date_published":"2017-02-22T00:00:00Z","date_updated":"2023-09-20T11:30:08Z","month":"02","article_processing_charge":"No","day":"22","type":"journal_article","project":[{"grant_number":"291734","_id":"25681D80-B435-11E9-9278-68D0E5697425","name":"International IST Postdoc Fellowship Programme","call_identifier":"FP7"},{"call_identifier":"FWF","_id":"26031614-B435-11E9-9278-68D0E5697425","name":"Quantum rotations in the presence of a many-body environment","grant_number":"P29902"}],"isi":1,"year":"2017","volume":118,"publist_id":"6225","intvolume":"       118","article_number":"085302","_id":"1133","language":[{"iso":"eng"}],"citation":{"mla":"Yakaboylu, Enderalp, and Mikhail Lemeshko. “Anomalous Screening of Quantum Impurities by a Neutral Environment.” <i>Physical Review Letters</i>, vol. 118, no. 8, 085302, American Physical Society, 2017, doi:<a href=\"https://doi.org/10.1103/PhysRevLett.118.085302\">10.1103/PhysRevLett.118.085302</a>.","ieee":"E.
