Vortex Rings and Mutual Drag in Trapped Bose-Einstein Condensates

B. Jackson, J. F. McCann, C. S. Adams

Published 1999-01-11, updated 1999-09-07Version 2

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.
