Chaotic shock waves of a Bose-Einstein condensate
Wenhua Hai, Qianquan Zhu, Shiguang Rong
It is demonstrated that the well-known Smale-horseshoe chaos exists in the time evolution of the one-dimensional Bose-Einstein condensate (BEC) driven by the time-periodic harmonic…

Discrete chaotic states of a Bose-Einstein condensate
Wenhua Hai, Shiguang Rong, Qianquan Zhu
We find the different spatial chaos in a one-dimensional attractive Bose-Einstein condensate interacting with a Gaussian-like laser barrier and perturbed by a weak optical lattice.…

Quantum Depletion of a Soliton Condensate
Guoxiang Huang, L. Deng, Jiaren Yan +1
We present rigorous results on the diagonalization of Bogoliubov Hamilto- nian for a soliton condensate. Using the complete and orthonomalized set of eigenfunction for the Bogoliub…
