摘要
We have studied the dynamic of Bose-Einstein condensate by solving numerically the Gross-Pitaevskii (GP) equation. We examine the periodic behaviour of the condensate in a shifted harmonic potential, and further demonstrated the tunneling of a condensate through a Gaussian energy barrier, which is inserted after the condensate has been excited by shifting the harmonic trapping potential to a side. Moreover, it is shown that the initial condensate evolves dynamically into two separate moving condensate after the tunneling time under certain conditions.
