Strong-coupling Bose polarons in one dimension: Condensate deformation and modified Bogoliubov phonons
We discuss the interaction of a quantum impurity with a one-dimensional degenerate Bose gas forming a Bose polaron. In three spatial dimension, the quasiparticle is typically well described by the extended Fröhlich model, in full analogy with the solid-state counterpart. This description, which assu...
