N2 - The structure and thermodynamics of up to 1000 vortices with and without strong columnar pins were studied using a continuum path integral quantum Monte Carlo (PIMC) simulation of the corresponding interacting bosons in (2+1)D. In the pure system, a triangular lattice phase was observed at low temperatures, which melted into an entangled liquid phase at higher temperature by a first order transition with a finite entropy jump. With increasing temperature, there was a transition from a Bose glass to an entangled defected liquid which is considerably smeared.
