Nonlocal Flow of Vortices in Narrow Superconducting Channels

I have reported a nonlocal effect in narrow superconducting channels, which arises in the absence of a driving current due to a long-range collective response of a one-dimensional vortex lattice and survives at distances of 3000 nm. The samples were thin amorphous superconductor Nb0.7Ge0.3 with thickness of 20 nm and width of 180 nm.
