Description/Abstract
We have modelled the 2d vortex state in superconductors numerically using Langevin dynamics. A dynamical phase diagram is obtained for a random pinning potential. We find a moving Bragg glass phase and for stronger pinning a moving transverse glass, in addition to pinned states and different kinds of plastic flow. We find that for both moving-glass phases transverse periodicity is maintained. Thus, in both moving glass phases a critical transverse force has been found. We study the critical transverse force as a function of pinning strength and temperature. Our results support the theory of Giamarchi and Le Doussal.
