论文摘要
在全息超级流体磁盘中，当旋转速度足够大时，我们发现通过在某些特定的旋转速度上合并几个单一电荷涡流，并在系统的中心形成巨大的涡流，并具有相位分层现象的阶参数参数。可以解释巨型涡流的形成，因为没有足够的空间用于标准涡旋晶格。继续增加旋转速度，巨大的涡流将消失，并且会出现超氟环。在巨大的涡流区域中，从绕组数和旋转速度测得的涡度数量始终满足线性Feynman关系。但是，当超级流体环开始出现时，尽管旋转速度正在增加，但磁盘中的涡流数将减小，其中大多数顺序参数被抑制。
In a holographic superfluid disk, when the rotational velocity is large enough, we find a giant vortex will form in the center of the system by merging several single charge vortices at some specific rotational velocity, with a phase stratification phenomenon for the order parameter. The formation of a giant vortex can be explained as there is not enough space for a standard vortex lattice. Keep increasing the rotational velocity the giant vortex will disappear and there will be an appearance of a superfluid ring. In the giant vortex region, the number of vortices measured from winding number and rotational velocity always satisfies the linear Feynman relation. However, when the superfluid ring starts to appear, the number of vortices in the disk will decrease though the rotational velocity is increasing, where most of the order parameter is suppressed.
