title: Set of measures to analyze the dynamics of nonequilibrium structures.
abstract: We present a class of statistical measures that can be used to quantify nonequilibrium surface growth. They are used to deduce information about spatiotemporal dynamics of model systems for spinodal decomposition and surface deposition. Pattern growth in the Cahn-Hilliard equation (used to model spinodal decomposition) are shown to exhibit three distinct stages. Two models of surface growth, namely, the continuous Kardar-Parisi-Zhang model and the discrete restricted-solid-on-solid model are shown to have different saturation exponents.
