Critical slowing down in the kinetic ising model; Evidence for the failure of the dynamical scaling hypothesis

We report computer simulations of critical slowing down in a two-dimensional kinetic Ising system consisting of a square n×n lattice with periodic boundary conditions. The results for the divergence of the relaxation times disagree with the predictions of the dynamical scaling hypothesis and with recent estimates obtained from a high-temperature expansion method. © 1972 The American Physical Society.
