Spectral flow in superconducting point contacts
N. B. Kopnin, V. M. Vinokur
We find that multiple Andreev reflections mediating the transport in superconducting point contacts are strongly affected by a small amount of impurities in the area of the contact…

Vortex Dynamics and the Problem of the Transverse Force in Clean Superconductors and Fermi Superfluids
N. B. Kopnin
We review the basic ideas and results on the vortex dynamics in clean superfluid Fermi systems. The forces acting on moving vortices are discussed including the problem of the tran…
