Dynamics of matter waves in optical traps

Abstract: We discuss our recent theoretical results on Bose-Einstein condensates (BECs), made of alkali-metal atoms, in optical traps. At zero temperature, the dynamics of a BEC is accurately described by a time-dependent matter-wave equation, the so-called Gross-Pitaevskii equation (GPE). By numerically solving the GPE we have investigated the bouncing and tunneling of a BEC through an optical barrier [1], the periodic emission of BEC pulses from an optical cavity [2], and the Josephson currents of a BEC in a double-well optical potential with oscillating height [2,3]. The relevance of our results for experiments is pointed out.
