Dipolar bright solitons and solitary vortices in a radial lattice
Dipolar bright solitons and solitary vortices in a radial lattice
Stabilizing vortex solitons with high values of the topological charge $S$ is a challenging issue in optics, studies of Bose-Einstein condensates (BECs), and other fields. To develop an approach to the solution of this problem, we consider a two-dimensional dipolar BEC under the action of an axisymmetric radially periodic lattice …
