Dynamics in a driven disordered vortex lattice: A numerical study

Using a repulsive vortex-vortex interaction model, we numerically investiga te the dynamics of vortices in a driven disordered two-dimensional supercon ductor. At low driving forces and temperatures, we have seen the evidence o f plastic and filamentary flow. At high driving forces and very low tempera tures, the evidence of an ordering of the moving vortices is seen in the fl ux flow regime. Our results are in agreement with the previous simulation r esults and recent experiments.
