Abstract
Effective gauge dynamics is proposed to study the disk-shaped nonsymmetric condensate in rotating trap, by which an analytical ground state is obtaine d explicitly and the stability of vortex mode is discussed in Thomas-Fermi limit. We also explain why total vorticity of the condensates is topologica lly conserved and quantized. (C) 2001 Elsevier Science B.V. All rights rese rved.
