DESCRIPTION:Polaron originaly means the conducting electron dressed by pho
 non cloud in a dielectric crystal\, described as a quasiparticle with a  
 medium dependent effective mass.\nRecently a cold-atomic many body system 
 mimics the polaron\, where an impurity atom immersed in atomic BEC is dres
 sed by Bogoliubov phonon cloud to be a "Bose polaron". The Bose polaron ha
 s been observed in some experiments in a very controlled way: dimensionali
 ty\, interaction between impurity and BEC atoms\, and property  of BEC ca
 n be designed almost at will.\nTheoretical works so far entirely assumed u
 niform systems\, although the experiments were done in traps.The local den
 sity approximation is not an adequate tool for detailed description of pol
 aron structure\, because the impurity itself causes inhomogeneity.\nSo\, w
 e directly calculate properties of Bose polarons in trap potentials\, taki
 ng care of the angular momentum conservation\, instead of the momentum con
 servation in uniform systems.\n\nhttps://events.ift.uni.wroc.pl/event/62/
