Phase transitions in vortex matter driven by bias current

The phase transition in vortex matter subjected to external magnetic field and bias current is described by the generalized Ginzburg-Landau equations with additional convective and effective field terms. Analytical and numerical solutions of this equation provide the interface between ordered and disordered vortex phases. The location of this interface boundary depends nonmonotonically on the strength of a bias current. We predict a sudden extension of the disordered vortex state across the entire sample at some critical value of the bias current.
