Abstract
We consider an atomic Bose-Einstein condensate loaded in a biased double-well trap with tunneling rate and interatomic interaction . The Bose-Einstein condensate is prepared such that all atoms are in the left well. We drive the system by sweeping the potential difference between the two wells. Depending on the interaction and the sweep rate , we distinguish three dynamical regimes: adiabatic, diabatic, and sudden and consider the occupation statistics of the final state. The analysis goes beyond mean-field theory and is complemented by a semiclassical picture.
