Three-dimensional vortex configurations in a rotating Bose-Einstein condensate

摘要: We consider a rotating Bose-Einstein condensate in harmonic trap and investigate numerically the behavior of wave function which solves Gross-Pitaevskii equation. Following recent experiments [P. Rosenbuch, V. Bretin, J. Dalibard, Phys. Rev. Lett. 89, 200403 (2002)], we study detail line single quantized vortex, has U or S shape. find that vortex can lie only $x\ensuremath{-}z$ $y\ensuremath{-}z$ plane. S-type vortices exist for all values angular velocity $\ensuremath{\Omega}$ while sufficiently large. compute energy various configurations with several three-dimensional structure vortices.
