Structure and evolution of quenched Ising clusters

摘要: The properties of domains generated following a quench from very high temperatures ($T\ensuremath{\gg}{T}_{c}$) to low are studied for an Ising model evolving under conserved or nonconserved dynamics. Before the clusters satisfy percolation statistics, since $T$ is too large interactions be relevant. However, after temperatures, we observe that largest still percolationlike distances in they described by same Hausdorff dimension as clusters. For short compact. At intermediate distances, appear more fractal than We interpret this regime crossover between constant density at and low-density not new type fractal.
