Dynamic Scaling and Universality of Two-Dimensional Random-Bond Potts Model

Short-time dynamics and universality are investigated for the random-bond Potts model with a trinary distribution of quenched randomness on a two-dimensional triangular lattice. The universal power-law scaling behaviour is applied to estimate the exponents z and β/v. Emphasis is placed on dynamic Monte Carlo evolutions for different multi-disorder amplitudes. Our results indicate that the quenched impurities cause a change of the critical universality.
