Abstract
We present results of Monte Carlo simulations of the gauge glass model in
three dimensions using exchange Monte Carlo. We show for the first time
clear evidence of the vortex glass ordered phase at finite temperature.
Using finite size scaling we obtain estimates for the correlation length
exponent, $\nu = 1.39 \pm 0.20$, the correlation function exponent,
$\eta = -0.47 \pm 0.07 $, and the dynamic exponent $z = 4.2 \pm
0.6$. Using our values for $z$ and $\nu$ we calculate the
resistivity exponent to be $s = 4.5 \pm 1.1$.
Finally, we provide a plausible lower
bound on the the zero-temperature stiffness exponent, $\theta \ge 0.18$.
