Contrasting the recent hydrodynamic shear with a Type-II superconducting fluxon lattice driven across a periodic pinning terrace. Quantized magnetic vortices (阿布里科索夫涡旋) depin under Lorentz torque, nucleating dynamic dislocations and elastic Bragg channels along chiral slip planes.
The terrace dropped four degrees kelvin and froze into a triangular pinning grid. 灰烬之下不再是连续的流体剪切，而是量子化的通量线在钉扎势阱间颤动。 When the drive current steps across the critical threshold, whole rows of vortices unlock at once, carving narrow Bragg channels through the ash.
Replaced the continuous shear Navier-Stokes approximation with discrete fluxon kinematics over a 2D washboard potential $U(r) = -U_0 \cos(K \cdot r)$. The lattice maintains hexagonal order below critical force $F_p$, then nucleates glide dislocations (滑移位错) along chiral slip planes. Density variance remained remarkably tight ($1.46 \times 10^{-4}$) against high frame motion (0.324), confirming that elastic channels preserve local flux conservation even during turbulent unpinning.
