Self-trapping of impurities in Bose-Einstein condensates: Strong attractive and repulsive coupling
- Abstract:
-
We study the interaction-induced localization - the so-called self-trapping - of a neutral impurity atom immersed in a homogeneous Bose-Einstein condensate (BEC). Based on a Hartree description of the BEC we show that - unlike repulsive impurities - attractive impurities have a singular ground state in 3d and shrink to a point-like state in 2d as the coupling approaches a critical value β*. Moreover, we find that the density of the BEC increases markedly in the vicinity of attractive impuriti...
