Dynamical phase diagram of driven vortices in high-Tc superconductors

Large-scale simulations on the current-driven three-dimensional frustrated anisotropic XY model with resistively-shunted junction dynamics have been performed to study the dynamical phase diagram in high-T-c superconductors. With the decrease of the current, a moving smectic is found between a moving Bragg glass and a moving liquid at high temperatures. The first-order phase transition between the moving Bragg glass and the moving smectic is clarified. At low temperatures, the moving Bragg glass can crossover to the (Creeping) Bragg glass directly. Interestingly, at very high currents, the moving Bragg glass is replaced by a highly disordered phase due to the activation of vortices and anti-vortices.
