旋转对称W型势阱中玻色-爱因斯坦凝聚环

提出一旋转对称磁光阱,这一势阱束缚的玻色-爱因斯坦凝聚是环形的．分别对无相互作用和强排斥作用两种极端情况的基态波函数做了计算．分析了凝聚形成的转变温度. 关键词：     

Crossover From Thermal Hopping to Quantum Tunneling in Ferromagnetic Particle

A W-shaped magneto-optical potential trap with axial symmetry is proposed.The Bose-Einstein condensate confined in the trap is ring-shaped.The ground state wave functions for two extreme cases,the noninteraction and strong repulsive limits,are calculated.The critical temperature is analyzed.
