Finite temperature ordering in the three-dimensional gauge glass

We present results of Monte Carlo simulations of the gauge glass model in three dimensions using the exchange Monte Carlo technique. We show clear evidence of the vortex glass ordered phase at finite temperature. Using finite size scaling we obtain estimates for the correlation length exponent nu=1.39+/-030, the correlation function exponent eta=-0.47+/-0.07, and the dynamic exponent z=4.2+/-0.6. Using our values for z and nu we calculate the resistivity exponent to be s=4.5+/-1.1. Finally, we provide a plausible lower bound on the zero-temperature stiffness exponent, theta greater than or equal to 0.18.
