Spin Hall effect generated by fluctuating vortices in type-II superconductors
Spin Hall effect generated by fluctuating vortices in type-II superconductors
We theoretically investigate the vortex spin Hall effect, i.e., a novel spin Hall effect driven by the motion of superconducting vortices, by focusing on the role of superconducting fluctuations. Within the BCS-Gor'kov microscopic approach combined with the Kubo formula, we find a strong similarity between the vortex spin Hall effect …
