Abstract
The 3D model with random in-plane couplings is simulated to model the phase diagram of a disordered type II superconductor as a function of temperature and randomness strength for fixed applied magnetic field. As increases to a critical , the first order vortex lattice melting line turns parallel to the axis, continuing down to low temperatures, rather than ending at a critical point. Above preliminary results suggest the absence of a phase coherent vortex glass.
