The research on dipolar gases constitutes one of the most promising future directions in the physics of ultracold gases, which is nowadays one of the most competive and interdisciplinary fields in atomic physics. The rotating properties of nondipolar gases are since the achievement of Bose-Einstein condensation (Nobel 2001) one of the most attractive topics in the physics of ultracold gases. The aim of this project is to combine these two research directions, analyzing the properties of ultracold rotating dipolar gases. The project will be split into two subareas. On one side, we shall analyze the physics of slowly rotating dipolar gases (no vortices), and in particular the time-of-flight expansion and the scissors modes. On the other side, we shall study the vortices in these gases, and in particular the critical rotation frequency for vortex formation, the shape of the vortex core, the vortex-vortex and vortexboundary interactions, vortex rings and the formation of vortex lattices.
