Current-voltage characteristics of three-dimensional anisotropic vortex glass model

The current-voltage characteristics of the three-dimensional anisotropic vortex glass model of disordered type-II superconductors with a uniformly field threading the system are studied by the Lagevin dynamics technique. Using the finite size scaling analysis, we show that in the presence of screening the correlation length exponent ν=2.6±0.35 which is compatible with recent results of the static Monte-Carlo simulations but it is considerably higher than that for the standard gauge glass model
