CORRELATIONS IN 2-DIMENSIONAL DOMAIN COARSENING

We present single-bit Monte Carlo simulations of the domain coarsening of a two dimensional binary system of size 1280 x 1280 from a quench at T = infinity to below the critical temperature T-c with emphasis on cluster distributions and correlations. We study both the conserved o rder parameter and the non-conserved order parameter. We measure the e volution of the mean cluster size and obtain both the distribution of cluster sizes and the correlations between clusters. Our results are c ompatible with recent experiments on Ostwald Ripening and numerical so lutions of the Cahn-Hilliard equation.
