Strong-coupling Bose polarons in one dimension: Condensate deformation and modified Bogoliubov phonons
J. Jager, R. Barnett, M. Will, M. Fleischhauer
Abstract
This work investigates Bose polarons in one dimension. The authors develop a model to take into account the backaction of the impurity on the condensate and where quantum fluctuations are described as modified Bogoliubov phonons on a deformed background.
