Spectral flow in Josephson junctions and effective Magnus force
Makhlin Yu.G., Volovik G. E.
Momentum production during the phase-slip process in SNS Josephson junction is discussed. It is caused by the spectral flow of bound states of fermions localized within the junction. This effectively reduces the Magnus force acting on vortices and thus provides an explanation for the experimental observation of a negligible Magnus force in 2D Josephson junction arrays. © 1995 American Institute of Physics.
