We approach the problem by introducing the concept of an “angulon”—a quantum rotor dressed by a quantum field—and reveal its quasiparticle properties using a combination of variational and diagrammatic techniques. Our theory predicts renormalization of the impurity rotational structure, such as that observed in experiments with molecules in superfluid helium droplets, in terms of a rotational Lamb shift induced by the many-particle environment. Furthermore, we discover a rich many-body-induced fine structure, emerging in rotational spectra due to a redistribution of angular momentum within the quantum many-body system."}],"doi":"10.1103/PhysRevLett.114.203001","publist_id":"5293","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","status":"public","date_published":"2015-05-18T00:00:00Z","issue":"20","isi":1,"publication":"Physical Review Letters","intvolume":"       114","language":[{"iso":"eng"}],"publisher":"American Physical Society","oa":1,"author":[{"full_name":"Schmidt, Richard","last_name":"Schmidt","first_name":"Richard"},{"orcid":"0000-0002-6990-7802","id":"37CB05FA-F248-11E8-B48F-1D18A9856A87","full_name":"Lemeshko, Mikhail","last_name":"Lemeshko","first_name":"Mikhail"}],"date_updated":"2025-09-23T10:40:28Z","month":"05","date_created":"2018-12-11T11:54:09Z","volume":114,"main_file_link":[{"open_access":"1","url":"http://arxiv.org/abs/1502.03447"}]}
