Phys. Rev. A 60, 4882–4885 (1999)Vortex rings and mutual drag in trapped Bose-Einstein condensatesReceived 11 January 1999; published in the issue dated December 1999 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. © 1999 The American Physical Society URL:
