Simulation of the resistive state of superconducting films in a magnetic field on the basis of the nonstationary ginzburg-landau equation

By numerical simulation of the temporal two-dimensional Ginzburg-Landau equation, we study the resistive state in superconducting bridges with dimensions ξ ≪ d ≪ λ. It is found that the basis of the resistive state here is, as for d ≫ λ, the vortical structures (vortices) whose motion defines the resistive state. It is shown that the motion of vortices is stochastic in a certain range of currents and magnetic fields.
