摘要：

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-metal 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. [S1050-2947(98)50303-4].
