DOMAIN-GROWTH PROPERTIES OF A 2-DIMENSIONAL KINETIC ISING-MODEL

The domain-growth properties of the two-dimensional single spin-flip k inetic Ising model with a Metropolis-type transition function and chec kerboard updating are investigated numerically with quenches from the high-temperature phase to temperatures in the ordered phase and to T(c ). Measuring the structure factor S(0, t) is-proportional-to t2x and t he autocorrelation function A(t) is-proportional-to t(-lambdaz) as a f unction of time, the effect of deterministic dynamics at T = 0 with x = 1.0 is followed throughout the ordered phase. At T < T(c), T almost- equal-to T(c), crossover from x = 1.0 to x = 0.5 is shown to occur wit h increasing time and even at T = T(c) the scaling exponents are still discernibly dependent on time. Lambda, however, is found to be unaffe cted in the whole temperature range.
