Persistent currents in a Bose-Einstein condensate in the presence of disorder
arXiv:cond-mat/0610830 · doi:10.1007/s10909-007-9504-9
Abstract
We examine bosonic atoms that are confined in a toroidal, quasi-one-dimensional trap, subjected to a random potential. The resulting inhomogeneous atomic density is smoothened for sufficiently strong, repulsive interatomic interactions. Statistical analysis of our simulations show that the gas supports persistent currents, which become more fragile due to the disorder.
