摘要: The nucleation of vortices and the resulting structures vortex arrays in dilute, trapped, zero-temperature Bose-Einstein condensates are investigated numerically. Vortices generated by rotating a three-dimensional, anisotropic harmonic atom trap. condensate ground state is obtained propagating Gross-Pitaevskii equation imaginary time. first appear at rotation frequency significantly larger than critical for stabilization, consistent with velocity mechanism nucleation. At higher frequencies, strongly influenced trap geometry.
