Dynamic phase-slip centers and the resistive state of a strong-nonequilibrium superconductor

Abstract

The model of dynamic phase-slip centers is considered for the resistive state of a strong-nonequilibrium, quasi-one-dimensional superconductor. It is shown that at a certain type of nonequilibrium, the factor ..gamma.. in the first time-derivative of the order parameter in the time-dependent Ginzburg--Landau equation can be made small. In this case the dynamic phase-slip centers in a two-dimensional space--time )x; t) have a structure quite similar to that of vortex lines in the mixed of a type II superconductor in ordinary space.
