First-Order Melting of a Moving Vortex Lattice: Effects of Disorder
arXiv:cond-mat/9610003 · doi:10.1103/PhysRevLett.78.2644
Abstract
We study the melting of a moving vortex lattice through numerical simulations with the current driven 3D XY model with disorder. We find that there is a first-order phase transition even for large disorder when the corresponding equilibrium transition is continuous. The low temperature phase is an anisotropic moving glass.
Important changes from original version. Finite size analysis of results has been added. Figure 2 has been changed. There is a new additional Figure. To be published in Physical Review Letters
