Abstract:

We present full three-dimensional numerical calculations of single vortex states in rotating dipolar condensates. We consider a Bose-Einstein condensate of C 52 r atoms with dipole-dipole and s -wave contact interactions confined in an axially symmetric harmonic trap. We obtain the vortex states by numerically solving the Gross-Pitaevskii equation in the rotating frame with no further approximations. We investigate the properties of a single vortex and calculate the critical angular velocity for different values of the s -wave scattering length. We show that, whereas the standard variational approach breaks down in the limit of pure dipolar interactions, exact solutions of the Gross-Pitaevskii equation can be obtained for values of the s -wave scattering length down to zero. The energy barrier for the nucleation of a vortex is calculated as a function of the vortex displacement from the rotation axis for different values of the angular velocity of the rotating trap. © 2009 The American Physical Society.

  • Even though 3D effects on vortex states should be more evident in cigar shaped configurations than in pancake ones, the stability of the condensate with a→0 is far more assured in the latter. Therefore, in order to reach stable configurations in the limit a=0 we restrict ourselves to pancake geometries; Góral, K., Santos, L., (2002) Phys. Rev.
