用变分方法和数值模拟研究了旋转囚禁玻色-爱因斯坦凝聚体中双曲弯曲涡线的最小能量位形。理论计算了涡线能量随旋转频率的变化，给出了自洽的涡数、曲率和形状。数值计算结果表明，弯曲比沿着z轴的直涡线更稳定，并且随着z的增加，xy平面上的涡位略有扩展。
The minimal energy configurations of hyperbolic bending vortex lines in the rotating trapped Bose–Einstein condensates are investigated by using a variational ansatz and numerical simulation. The theoretical calculation of the energy of the vortex lines as a function of the rotation frequency gives self-consistently vortex number, curvature and configuration. The numerical results show that bending is more stable than straight vortex line along the z-axis, and the vortex configuration in the xy-plane has a little expansion by increasing z.
