Stationary wave patterns generated by an impurity moving with supersonic velocity through a Bose-Einstein condensate
arXiv:0902.1317 · doi:10.1103/PhysRevA.79.053619
Abstract
Formation of stationary 3D wave patterns generated by a small point-like impurity moving through a Bose-Einstein condensate with supersonic velocity is studied. Asymptotic formulae for a stationary far-field density distribution are obtained. Comparison with three-dimensional numerical simulations demonstrates that these formulae are accurate enough already at distances from the obstacle equal to a few wavelengths.
