Critical dynamics of the random-bond Potts ferromagnet with multi-disorder amplitudes on a triangular lattice

Abstract Critical behavior in short-time dynamics is investigated by a Monte Carlo study for the random-bond Potts ferromagnet with a trinary distribution of quenched disorders on two-dimensional triangular lattices. The universal dynamic scaling is verified and applied to estimate the critical exponents θ , z and β / ν for several realizations of the trinary distribution. Our critical scaling analysis strongly indicates that the bond randomness influences the critical universality.
