Vortex solitons in dipolar Bose-Einstein condensates
Vortex solitons in dipolar Bose-Einstein condensates
We predict solitary vortices in quasiplanar condensates of dipolar atoms, polarized parallel to the confinement direction, with the effective sign of the dipole-dipole interaction inverted by means of a rapidly rotating field. Energy minima corresponding to vortex solitons with topological charges $\ensuremath{\ell}=1$ and 2 are predicted for moderately strong dipole-dipole …
