Monte Carlo Studies of Spinodal Decomposition in the 2d Kinetic Ising Model
Results obtained from extensive Monte Carlo simulations of domain growth in the two dimensional spin-exchange kinetic Ising model with equal numbers of up and down spins are presented. Using different measures of domain size — including the pair-correlation function, the energy, and circularly-averaged structure factor — the domain size is determined as a function of time (at T = 0.5 Tc) for times up to 106 Monte Carlo steps. The growth law R(t) = A + B t1/3 is found to provide an excellent fit to the data. Preliminary work, using the Connection Machine 2 (CM2) parallel-processor is also described.
