Abstract

We used the Multilevel Monte Carlo method to simulate and investigate the phases of vortex matter in anisotropic superconductors with extended columnar defects. Introducing low amounts of defects, B_φ = 50 G, we found that the vortex melting process proceeded in two stages. Vortices in the nanocrystalline phase melted into the nanoliquid phase, via a first-order phase transition, and then into the homogeneous liquid phase as the temperature was raised.
