Contribution

It provides a theoretical analysis of the factors affecting persistent current stability in toroidal BECs and discusses potential methods for their control and observation.

Findings

Stability of currents can be tuned by system parameters

Difficulties in creating persistent currents are identified

Detection methods for persistent currents are analyzed

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.
