Using the time-dependent Ginzburg-Landau equations, we study vortex motion driven by an applied current in two-dimensional superconductors in the presence of a physical boundary. At smaller sourced currents the vortex lattice moves as a whole, with each vortex moving at the same velocity. At the larger sourced current, the vortex motion is organized into channels, with vortices in channels closer to the sample edges moving faster than those farther away from sample edges, opposite the Poiseuille flow of basic hydrodynamics in which the velocity is lowest at the boundaries. At intermediate currents, a stick-slip motion of the vortex lattice occurs in which vortices in the channel at the boundary break free from the Abrikosov lattice, accelerate, move past their neighbors, and then slow down and reattach to the vortex lattice, at which point the stick-slip process starts over. These effects could be observed experimentally, e.g., using fast scanning microscopy techniques.

反泊肃叶流：增加超导体边缘的涡流速度

使用时间相关的 Ginzburg-Landau 方程，我们研究了在存在物理边界的情况下，二维超导体中由施加电流驱动的涡旋运动。在较小的源电流下，涡流晶格作为一个整体移动，每个涡流以相同的速度移动。在较大的源电流下，涡流运动被组织成通道，靠近样品边缘的通道中的涡流比远离样品边缘的通道中的涡流运动得更快，这与基本流体动力学的泊肃叶流相反，其中速度在边界处最低。在中间电流下，涡流晶格发生粘滑运动，其中边界处通道中的涡流从 Abrikosov 晶格中脱离，加速，越过它们的邻居，然后减速并重新附着到涡旋晶格上，此时粘滑过程重新开始。这些效果可以通过实验观察到，例如，使用快速扫描显微镜技术。
