Renormalization group approach to the Fröhlich polaron model: application to impurity-BEC problem

F Grusdt, YE Shchadilova, AN Rubtsov, E Demler - Scientific reports, 2015 - nature.com
When a mobile impurity interacts with a many-body system, such as a phonon bath, a
polaron is formed. Despite the importance of the polaron problem for a wide range of …

Motional coherence of fermions immersed in a Bose gas

Observation of the phononic Lamb shift with a synthetic vacuum

T Rentrop, A Trautmann, FA Olivares, F Jendrzejewski… - Physical Review X, 2016 - APS
In contrast to classical empty space, the quantum vacuum fundamentally alters the
properties of embedded particles. This paradigm shift allows one to explain the discovery of …

Collective excitations of a Bose–Einstein condensate of hard-core bosons and their mediated interactions: from two-body bound states to mediated superfluidity
