Abstract

We study the ground states of rotating atomic Bose-Einstein condensates with dipolar interactions. We present the results of numerical studies on a periodic geometry which show vortex lattice ground states of various symmetries: triangular and square vortex lattices, "stripe crystal" and "bubble crystal". We present the phase diagram (for systems with a large number of vortices) as a function of the ratio of dipolar to contact interactions and of the chemical potential. We discuss the experimental requirements for observing transitions between vortex lattice groundstates via dipolar interactions. We finally investigate the stability of mean-field supersolid phases of a quasi-2D non-rotating Bose gas with dipolar interactions.
