title: Multiscaling of energy correlations in the random-bond potts model
abstract: We numerically calculate the exponents governing the disorder averaged and fixed-sample decay of the energy-energy correlator in the q-state random-bond Potts model. Our results are in good agreement with a two-loop expansion around q=2 recently found from perturbative renormalization group techniques, fulfill the correlation length bound nu>/=2/d, and give further evidence against replica symmetry breaking in this class of models.
