Abstract
We calculate the new dynamic exponent θ of the 4-state Potts model, using short-time simulations. Our estimates θ 1 = − 0.0471 ( 33 ) and θ 2 = − 0.0429 ( 11 ) obtained by following the behavior of the magnetization or measuring the evolution of the time correlation function of the magnetization corroborate the conjecture by Okano et al. [Nucl. Phys. B 485 (1997) 727]. In addition, these values agree with previous estimate of the same dynamic exponent for the two-dimensional Ising model with three-spin interactions in one direction, that is known to belong to the same universality class as the 4-state Potts model. The anomalous dimension of initial magnetization x 0 = z θ + β / ν is calculated by an alternative way that mixes two different initial conditions. We have also estimated the values of the static exponents β and ν. They are in complete agreement with the pertinent results of the literature.
