Topological phases and circulating states of Bose-Einstein condensates
K. G. Petrosyan, L. You
abstract: We show that the quantum topological effect predicted by Aharonov and Casher
(AC effect) [Phys. Rev. Lett. 53, 319 (1984)] may be used to create circulating
states of magnetically trapped atomic Bose-Einstein condensates (BEC). A simple
experimental setup is suggested based on a multiply connected geometry such as
a toroidal trap or a magnetic trap pinched by a blue-detuned laser. We give
numerical estimates of such effects within the current atomic BEC experiments,
and point out some interesting properties of the associated quantized
circulating states.
