Amorphous vortex glass phase in strongly disordered superconductors

We introduce a model describing vortices in strongly disordered three-dimensional superconductors. The model focuses on the topological defects, i.e., dislocation lines, in an elastic description of the vortex lattice. The model is studied using Monte Carlo simulations, revealing a glass phase at low temperatures, separated by a continuous phase transition to the high temperature resistive vortex liquid phase. The critical exponents nuapproximate to1.3 and etaapproximate to-0.4 characterizing the transition are obtained from finite size scaling.
