Phys. Rev. E 70, 056134 (2004) [8 pages]Critical behavior of the two-dimensional random-bond Potts model: A short-time dynamic approachReceived 28 July 2004; published 29 November 2004 The short-time critical dynamics of the two-dimensional eight-state random-bond Potts model is investigated with large-scale Monte Carlo simulations. Dynamic relaxation starting from a disordered and an ordered state is carefully analyzed. The continuous phase transition induced by disorder is studied, and both the dynamic and static critical exponents are estimated. The static exponent β∕ν shows little dependence on the disorder amplitude r, while the dynamic exponent z and static exponent 1∕ν vary with the strength of disorder. © 2004 The American Physical Society URL:
