Pinning Potential

Nonequilibrium phase transitions of vortex matter with a strong random pinning potential in layered superconductors are investigated by the three-dimensional frustrated anisotropic XY model and resistively-shunted junction dynamics at low, middle and high-temperatures, respectively. It is found that a disorder to order phase transition driven by an external current can be obtained at a low-temperature, however, a reordering configuration does not occur at a high-temperature. With the competition between thermal noise, disorder pins and current, the vortex matter can even show the reordering process twice at an intermediate temperature, giving a clear evidence of dc driven vortex lattice reorganization.

Moving Vortex

The current-driven three-dimensional frustrated anisotropic XY model with strong disorder is simulated to model the moving vortex matter in layered superconductors. The equilibrium disordered state can be driven to a moving Bragg glass (BrG) by applying an external current. As the pinning strength increases, the moving BrG can melt into a moving smectic via a first-order phase transition.
