Exact solutions to the three-dimensional Gross-Pitaevskii equation with
modulated radial nonlinearity [PDF]
Wei-Ting Wang, Ying-Ying Li, Shi-Jie YangWe study the Bose-Einstein condensate trapped in a three-dimensional spherically symmetrical potential. Exact solutions to the stationary Gross-Pitaevskii equation are obtained for properly modulated radial nonlinearity. The solutions contain vortices with different winding numbers and exhibit the shell-soliton feature in the radial distributions.View original: http://arxiv.org/abs/1302.0445
