Vortex Refraction at Tilted Superconductor-Normal Metal Interfaces
arXiv:2507.22441 · doi:10.1103/ld3z-kkmp
Abstract
We derive a refraction law for superconducting vortices at superconductor/normal metal interfaces. Simulations of the proximity effect under tilted geometries confirm this law and reveal vortex trapping for low effective mass. Under transport currents, we find core displacements due to differing vortex viscosities in the superconductor and normal metal. These results clarify vortex dynamics in proximity-coupled systems and offer design principles for high-current coated superconducting devices.
