Coherence and instability in a driven Bose–Einstein condensate: a fully dynamical number-conserving approach
Billam, T.P.; Gardiner, S.A.
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.
