摘要: We study the generation of vortices in rotating Bose-Einstein condensates, a situation that has been realized recent experiment [K. W. Madison, F. Chevy, Wohlleben, and J. Dalibard, Phys. Rev. Lett. 84 806 (2000)]. By combining linear stability analysis with global optimization nonlinear free-energy functional, we regimes can be reached current experiments. find hysteresis phenomenon vortex nucleation due to metastabilization vortexless condensate. also prove for fast enough trap, ground state condensate hosts one or more bent lines.
