Decoherence of Bose-Einstein condensates in microtraps
arXiv:cond-mat/0212415 · doi:10.1103/PhysRevA.69.043602
Abstract
We discuss the impact of thermally excited near fields on the coherent expansion of a condensate in a miniaturized electromagnetic trap. Monte Carlo simulations are compared with a kinetic two-component theory and indicate that atom interactions can slow down decoherence. This is explained by a simple theory in terms of the condensate dynamic structure factor.
