TY - JOUR A1 - Henkel, Carsten A1 - Gardiner, Simon A. T1 - Decoherence of Bose-Einstein condensates in microtraps N2 - 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 Y1 - 2004 UR - https://publishup.uni-potsdam.de/frontdoor/index/index/docId/14430 ER -
