报告摘要:This talk will report our recent results on ground states of two dimensional spin-1 Bose-Einstein condensates trapped in harmonic-like potentials with attractive mean-field interaction. Two conserved quantities, the number of atoms and the total magnetization are involved in. The conditions for existence and non-existence of the ground states have been established according to the relations among the mean-field interaction, spin-exchange interaction and the total magnetization. Furthermore, as the parameters of the mean-field interaction and spin-exchange interaction approach the thresholds, the asymptotic behavior of the ground states are presented in details. This talk is based on a joint work with Dr. Yuzhen Kong and Qingxuan Wang.
