Common universality class for the three-dimensional vortex glass and chiral glass

We present a Monte Carlo study of the d=3 gauge glass and the XY spin glass models in the vortex representation. We investigate the critical behavior of these models by a scaling analysis of the linear resistivity and current-voltage characteristics, both in the limits of zero and strong screening of the vortex interactions. Without screening, both models show a glass transition at a finite temperature and, within the numerical accuracy, exhibit the same critical exponents: z approximate to 3.1 and v=1.3+/-0.3 With strong screening, the finite-temperature glass transition is destroyed in both cases and the same exponent v=1.05+/-0.1 is found at the resulting zero-temperature transition.
