DOMAIN GROWTH CONTROLLED BY INTERFACIAL TRANSPORT IN 2-DIMENSIONAL SYSTEMS

Domain growth is studied for a conserved order parameter when the inte rfacial particle current dominates the material transport in a two-dim ensional system. A simple geometrical model suggests that the typical domain size increases as t(1/4) for long times. This behavior is suppo rted by Monte Carlo simulations performed in a half-filled lattice gas taking the first-and second-neighbor jumps and interactions into cons ideration.
