中文摘要：
在幺正极限附近研究了处于旋转外势中费米气体的量子化涡旋动力学.选取适当的试探波函数并利用含时变分法,得到了小振幅涡旋运动方程及描述其反常激发模式的解.详细讨论了在幺正极限附近的反常模式产生的条件.结果显示系统囚禁外势的临界转动频率在幺正极限附近随粒子间相互作用参数的增加而变大,而涡旋进动的周期则随着粒子间相互作用参数的增加而减小.
英文摘要：
We investigate the dynamics of a quantized vortex in a trapped superfluid Fermi gas near the unitarity limit. By taking a trial wave function for the order-parameter of a condensate in a rotating axisymmetric trap confinement and using a time-dependent variational analysis we obtain the equations of motion and their solutions for anomalous mode. The results show that the critical rotating frequency of the trap increases when the system ranges from the left to the right side of the unitarity limit, while the period of the vortex decreases in this regime.
