Here are preliminary results from the BEC calculation. Initial wavefunction is a Gaussian wavepacket. This condition has been used successfully in many cases.
Time is indicatd by yellowish numbers at the upper left corners.
Optical Lattice is dragged to the right. Time is indicatd by yellowish numbers at the upper left corners. Optical Lattice is dragged to the right. Only the front end of the BEC is dragged. For non-interacting case, BEC is dragged without much deformation.
