Abstract

We carry out Monte Carlo simulations of the three dimensional (3D) lattice London superconductor in zero applied magnetic field, making a detailed finite size scaling analysis of the Meissner transition. We find that the magnetic penetration length λ, and the correlation length ξ, scale as λ~ ξ~ |t|^-ν, with ν= 0.66 ± 0.03, consistent with ordinary 3D XY universality, ν_XY ~ 2/3. Our results confirm the anomalous scaling dimension of magnetic field correlations at T_c.
