Abstract
We numerically integrate the 3-D time-dependent Gross-Pitaevskii equation to investigate dynamical transitions of the trapped Bose-Einstein condensate (BEC) from an initial non-vortex state to a steady vortex lattice state after the trigger of the rotation. We use the splitting-fourier method as a numerical scheme to perform stable 3-D numerical simulations with high computational efficiency. We present characteristic 3-D non-steady dynamics of vortices, i.e., the vortex penetration, the stochasitc vortex wandering, the vortex lattice vibration, etc.
