Comment on "Effects of Point Defects on the Phase Diagram of Vortex States in High-Tc Superconductors in the B || c Axis"

Abstract

We comment on a recent work by Nonomura and Hu who simulated the 3D XY model for a type-II superconductor in an applied magnetic field, in the presence of uncorrelated point randomness. We clarify the nature of the "vortex slush" state that they found, and argue that this state is unstable in the thermodynamic limit.
