摘要

We propose a modified voter model with locally conserved magnetization and investigate its phase ordering dynamics in two dimensions in numerical simulations. Imposing a local constraint on the dynamics has the surprising effect of speeding up the phase ordering process. The system is shown to exhibit a 縮放律 regime characterized by algebraic domain growth, at odds with the logarithmic coarsening of the standard voter model. A phenomenological approach based on cluster 擴散 and similar to Smoluchowski ripening correctly predicts the observed 縮放律 regime. Our analysis exposes unexpected complexity in the phase ordering dynamics without 熱力學 potential.
