Abstract
Simulations of 2D vortex lattice melting in superconducting films are performed in the London limit. A detailed finite size scaling test of the theory of dislocation mediated melting in 2D indicates a weakly first order transition, and no hexactic liquid phase. However, the shear modulus vanishes discontinuously at melting, with a value in good agreement with this theory.Keywords
