Recently, it was predicted that a superfluid can acquire angular momentum via an alternative, microscopic route -- namely, through interaction with rotating impurities, forming so-called `angulon quasiparticles' [Phys. Rev. Lett. 114, 203001 (2015)]. The angulon instabilities correspond to transfer of a small number of angular momentum quanta from the impurity to the superfluid, as opposed to vortex instabilities, where angular momentum is quantized in units of ℏ per atom. Furthermore, since conventional impurities (such as molecules) represent three-dimensional (3D) rotors, the angular momentum transferred is intrinsically 3D as well, as opposed to a merely planar rotation which is inherent to vortices. Herein we show that the angulon theory can explain the anomalous broadening of the spectroscopic lines observed for CH 3 and NH 3 molecules in superfluid helium nanodroplets, thereby providing a fingerprint of the emerging angulon instabilities in experiment."]},"publication":"Physical Review Materials","day":"08","type":"journal_article","status":"public","_id":"994","department":[{"_id":"MiLe","tree":[{"_id":"ResearchGroups"},{"_id":"IST"}]}],"date_updated":"2023-09-22T09:53:42Z","creator":{"login":"apreinsp","id":"4435EBFC-F248-11E8-B48F-1D18A9856A87"},"main_file_link":[{"url":"https://arxiv.org/abs/1705.09220","open_access":"1"}],"scopus_import":"1","intvolume":" 1","month":"08","abstract":[{"lang":"eng"}],"oa_version":"Submitted Version","ec_funded":1,"volume":1,"issue":"3","publication_status":"published","language":[{}]}]
