Three-dimensional solitons and vortices in dipolar Bose-Einstein condensates
arXiv:0708.2355 · doi:10.1016/j.physleta.2008.01.010
Abstract
Three-dimensional solitary and vortex structures in Bose-Einstein condensates are studied in the framework of Gross-Pitaevskii model including the simultaneous action of local cubic-quintic nonlinearity and nonlocal dipole-dipole interactions. Nonlocal interactions are shown to change significantly the formation threshold and the numbers of atoms confined into the coherent structures. An appearance of robust high-order () three-dimensional vortices is revealed.
