Abstract
Vortex states of weakly-interacting Bose-Einstein condensates confined in three-dimensional rotating harmonic traps are investigated numerically at zero temperature. The ground state in the rotating frame is obtained by propagating the Gross-Pitaevskii (GP) equation for the condensate in imaginary time. The total energies between states with and without a vortex are compared, yielding critical rotation frequencies that depend on the anisotropy of the trap and the number of atoms. Vortices in nonrotating traps are found to be stationary for sufficiently large numbers of atoms and small off-center displacements. The relationship between vortex stability and bound core states is explored.Citation
