Landau Física, Astronomía y Matemáticas Ising Model Domain Growth Phase Separation Compressible Model Large scale Monte Carlo simulations have been used to study long-time domain growth behavior in a compressible, two-dimensional Ising model undergoing phase separation. The system is quenched below the transition temperature from a random spin state, and we investigated the late-time domain size growth law, R(t) = A + Bt n. For "lattice mismatched" systems, we found n = 0.224 ± 0.004 which deviates significantly from the Lifshitz-Slyozov value of n = 1/3 for late-time growth . For a compressible model with no mismatch, we find only a slight deviation from n = 1/3. These results strongly suggest that we do not yet fully understand domain growth. 2008 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46413551002 en http://www.redalyc.org/revista.oa?id=464 Brazilian Journal of Physics application/pdf Sociedade Brasileira de Física Brazilian Journal of Physics (Brasil) Num.1 Vol.38 |
