Multiply-connected Bose-Einstein condensed alkali gases: Current-carrying states and their decay
arXiv:cond-mat/9711106 · doi:10.1103/PhysRevA.57.R1505
Abstract
The ability to support metastable current-carrying states in multiply-connected settings is one of the prime signatures of superfluidity. Such states are investigated theoretically for the case of trapped Bose condensed alkali gases, particularly with regard to the rate at which they decay via thermal fluctuations. The lifetimes of metastable currents can be either longer or shorter than experimental time-scales. A scheme for the experimental detection of metastable states is sketched.
