Short-time dynamics and magnetic critical behavior of the two-dimensional random-bond Potts model

Abstract

The critical behavior in the short-time dynamics for the random-bond Potts ferromagnet in two dimensions is investigated by short-time dynamic Monte Carlo simulations. The numerical calculations show that this dynamic approach can be applied efficiently to study the scaling characteristic, which is used to estimate the critical exponents θ, β/ν, and z, for quenched disordered systems from the power-law behavior of the kth moments of magnetization.
