Vortex solitons in dipolar Bose-Einstein Condensates

We predict solitary vortices in quasi-planar 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 {% \ell}=1 and 2 are predicted for moderately strong dipole-dipole interaction, using an axisymmetric Gaussian ansatz. The stability of the solitons with $\ell =1$ is confirmed by full 3D simulations, whereas their counterparts with $\ell =2$ are found to be unstable against splitting into a set of four fragments (quadrupole).
