Stability of Persistent Currents in a Bose-Einstein Condensate Confined in a Toroidal Trap

Article

Abstract

Motivated by recent experiments in Bose-Einstein condensed atoms that have been confined in toroidal traps, we examine the stability of persistent currents in such systems. We investigate the extent that the stability of these currents may be tunable, and the possible difficulties in their creation and detection.
