利用AdS/CFT对应，我们探讨了具有恒定角速度的圆盘中强耦合超流涡旋的动力学。在涡旋晶格中的每一个涡旋都是通过直接检查它们的相位而用涡度1量子化的。当盘的角速度大于临界值时，第一涡将如理论预测所预期的那样被激发。随后的两个和更多的涡流也产生了越来越多的旋转盘，导致显着的角速度的阶跃转变，激发每个单独的涡流。当涡数足够大时，涡的密度与角速度成线性关系，这与费曼关系很好地吻合。
By utilizing the AdS/CFT correspondence, we explore the dynamics of strongly coupled superfluid vortices in a disk with constant angular velocity. Each vortex in the vortex lattice is quantized with vorticity one from the direct inspection of their phases. As the angular velocity of the disk is greater than a critical value, the first vortex will be excited as expected from theoretical predictions. The subsequent two and more vortices are also generated by increasingly rotating the disk, resulting in the remarkable step transitions for the angular velocity to excite each individual vortex. When the vortex number is large enough, the density of vortices is found to be linearly proportional to the angular velocity, which matches the Feynman relation very well.
