介观超导Corbino超导体中的非常规涡旋动力学
Unconventional Vortex Dynamics in Mesoscopic Superconducting Corbino Disks
摘要：
涡旋物质的离散壳层结构强烈影响着介观超导Corbino盘中的磁通动力学。虽然在大的和非常小的圆盘中的动力学行为是很好理解的，但在中等大小的区域中，由于涡壳之间的可伸缩性，它变得更加复杂和不寻常。我们展示了非常规的涡旋动力学（反转壳速度相对于梯度驱动力）和角熔化（从边界处的剪切应力是最小的，向中心传播）在介观Corbino磁盘。
英文摘要：
The discrete shell structure of vortex matter strongly influences the flux dynamics in mesoscopic superconducting Corbino disks. While the dynamical behavior is well understood in large and in very small disks, in the intermediate-size regime it occurs to be much more complex and unusual, due to (in)commensurability between the vortex shells. We demonstrate unconventional vortex dynamics (inversion of shell velocities with respect to the gradient driving force) and angular melting (propagating from the boundary where the shear stress is minimum, towards the center) in mesoscopic Corbino disks.
