Polaron formation in the vicinity of a narrow Feshbach resonance in atomic and exciton-polariton condensates
Wim Casteels, Michiel Wouters
The polaronic system consisting of an impurity in a dilute Bose-Einstein condensate is considered in the presence of a narrow Feshbach resonance. For this purpose a coupled-channel…

Diagrammatic Monte Carlo study of the acoustic and the BEC polaron
Jonas Vlietinck, Wim Casteels, Kris Van Houcke +3
We consider two large polaron systems that are described by a Fröhlich type of Hamiltonian, namely the Bose-Einstein condensate (BEC) polaron in the continuum and the acoustic pola…

Bipolarons and multi-polarons consisting of impurity atoms in a Bose-Einstein condensate
W. Casteels, J. Tempere, J. T. Devreese
The variational Feynman formalism for the polaron, extended to an all-coupling treatment of bipolarons, is applied for two impurity atoms in a Bose-Einstein condensate. This shows…
