Rotational properties of non-dipolar and dipolar Bose-Einstein condensates confined in annular potentials
arXiv:1207.6505 · doi:10.1103/PhysRevA.87.033615
Abstract
We investigate the rotational response of both non-dipolar and dipolar Bose-Einstein condensates confined in an annular potential. For the non-dipolar case we identify certain critical rotational frequencies associated with the formation of vortices. For the dipolar case, assuming that the dipoles are aligned along some arbitrary and tunable direction, we study the same problem as a function of the orientation angle of the dipole moment of the atoms.
