Self-Trapping of Bose-Einstein Condensates in an Optical Lattice: the Effect of the System Dimension
Ju-Kui Xue, Ai-Xia Zhang, Jie Liu
In the present paper, we investigate the dynamics of a Bose-Einstein condensates (BEC) loaded into an deep optical lattice of 1D, 2D and 3D, both analytically and numerically. We f…

Collective excitations of a Bose-Einstein condensate in an anharmonic trap
Guan-Qiang Li, Li-Bin Fu, Ju-Kui Xue +2
We investigate the collective excitations of a one-dimensional Bose-Einstein condensate (BEC) with repulsive interaction between atoms in a quadratic plus quartic trap. By using th…
