Domain statistics in coarsening systems
نویسندگان
چکیده
We study the domain number and size distributions in the one-dimensional Ising and q-state Potts models subject to zero-temperature Glauber dynamics. The survival probability of a domain S(t);t and an unreacted domain Q1(t);t 2d are characterized by two independent nontrivial exponents. For the Ising case, we find c50.126 and d51.27 using numerical simulations. We develop an independent interval approximation that predicts the qualitative behavior of the domain distribution and provides good estimates for the exponents. Exact results for the domain distribution are also obtained in several solvable cases. @S1063-651X~97!00110-4#

Exact results for curvature-driven coarsening in two dimensions.
We consider the statistics of the areas enclosed by domain boundaries ("hulls") during the curvature-driven coarsening dynamics of a two-dimensional nonconserved scalar field from a disordered initial state. We show that the number of hulls per unit area that enclose an area greater than A has, for large time t, the scaling form Nh(A,t)=2c/(A+lambdat), demonstrating the validity of dynamical sc...
متن کاملAnomalous coarsening and glassy dynamics
An overview of the related topics of anomalous coarsening and glassy dynamics is given. In anomalous coarsening, the typical domain size of an ordered phase grows more slowly with time than the power law dependence that is usually observed, for example, in magnetic systems. We discuss how anomlaous coarsening may arise through domain-size dependent energy barriers in the coarsening process. We ...
متن کاملIrreversibility and the statistics of grain boundaries
For most coarsening systems, we do not understand how or why the evolution produces a statistical steady state. In a paper appearing in Physical Review B, Katayun Barmak at Carnegie Mellon University and colleagues present theoretical arguments to explain the statistics of grain boundaries in a polycrystalline material after the occurrence of coarsening due to annealing [1]. Recent experimental...
متن کاملCoarsening with nontrivial in-domain dynamics: Correlations and interface fluctuations.
Using numerical simulations we investigate the space-time properties of a system in which spirals emerge within coarsening domains, thus giving rise to nontrivial internal dynamics. Initially proposed in the context of population dynamics, the studied six-species model exhibits growing domains composed of three species in a rock-paper-scissors relationship. Through the investigation of differen...
متن کاملHeterogeneous dynamics of coarsening systems.
We show by means of experiments, theory, and simulations that the slow dynamics of coarsening systems displays dynamic heterogeneity similar to that observed in glass-forming systems. We measure dynamic heterogeneity via novel multipoint functions which quantify the emergence of dynamic, as opposed to static, correlations of fluctuations. Experiments are performed on a coarsening foam using tim...
