Vortex Rings and Mutual Drag in Trapped Bose-Einstein Condensates
arXiv:cond-mat/9901087 · doi:10.1103/PhysRevA.60.4882
Abstract
We study the drag on an object moving through a trapped Bose-Einstein condensate, and show that finite compressibility leads to a mutual drag, which is subsequently suppressed by the formation of a vortex ring.
