Effects of disorder on quantum fluctuations and superfluid density of a Bose-Einstein condensate in a two-dimensional optical lattice
Ying Hu, Zhaoxin Liang, Bambi Hu
We investigate a Bose-Einstein condensate trapped in a 2D optical lattice in the presence of weak disorder within the framework of the Bogoliubov theory. In particular, we analyze…

Gap Solitons and Bloch Waves in Nonlinear Periodic Systems
Yongping Zhang, Zhaoxin Liang, Biao Wu
We comprehensively investigate gap solitons and Bloch waves in one-dimensional nonlinear periodic systems. Our results show that there exists a composition relation between them: B…

Exact nonlinear Bloch-state solutions for Bose-Einstein condensates in a periodic array of quantum wells
Rui Xue, Z. X. Liang, Weidong Li
A set of exact closed-form Bloch-state solutions to the stationary Gross-Pitaevskii equation are obtained for a Bose-Einstein condensate in a one-dimensional periodic array of quan…
