Matter-wave solitons and finite-amplitude Bloch waves in optical lattices with a spatially modulated nonlinearity
Jie-Fang Zhang, Yi-Shen Li, Jianping Meng +2
We investigate solitons and nonlinear Bloch waves in Bose-Einstein condensates trapped in optical lattices. By introducing specially designed localized profiles of the spatial modu…

Exact exact solutions of the Gross-Pitaevskii equation for stable vortex modes
Lei Wu, Lu Li, Jie-Fang Zhang +3
We construct exact solutions of the Gross-Pitaevskii equation for solitary vortices, and approximate ones for fundamental solitons, in 2D models of Bose-Einstein condensates with a…
