Gross-Pitaevskii mean-field theory for a trapped, rotating Bose-Einstein condensate: quantized vortex detection, a bound vortex-antivortex pair with canceling net winding, ground-state relaxation, the critical rotation frequency for vortex nucleation, a vortex genuinely precessing in real time, self-focusing wave collapse, and the Casimir vacuum force.
