Coherence and instability in a driven Bose–Einstein condensate : a fully dynamical number-conserving approach.

Billam, T. P. and Gardiner, S. A. (2012) 'Coherence and instability in a driven Bose–Einstein condensate : a fully dynamical number-conserving approach.', New journal of physics., 14 . 013038.

Abstract

We consider a Bose–Einstein condensate driven by periodic delta-kicks. In contrast to first-order descriptions, which predict rapid, unbounded growth of the noncondensate in resonant parameter regimes, the consistent treatment of condensate depletion in our fully time-dependent, second-order description acts to damp this growth, leading to oscillations in the (non)condensate population and the coherence of the system.
