Vortex-induced dissipation in narrow current-biased thin-film superconducting strips
Vortex-induced dissipation in narrow current-biased thin-film superconducting strips
A vortex crossing a thin-film superconducting strip from one edge to the other, perpendicular to the bias current, is the dominant mechanism of dissipation for films of thickness $d$ on the order of the coherence length $\ensuremath{\xi}$ and of width $w$ much narrower than the Pearl length $\ensuremath{\Lambda}\ensuremath{\gg}w\ensuremath{\gg}\ensuremath{\xi}$.
