标题： Voter models with conserved dynamics

摘要： 我们提出了一种具有局部守恒磁化的改进投票者模型，并在二维情况下通过数值模拟研究其相分离动力学。 对动力学施加局部约束意外地加快了相分离过程。 该系统表现出由代数域增长表征的标度区域，这与标准投票者模型的对数粗化相矛盾。 一种基于团簇扩散且类似于Smoluchowski粗化的现象学方法正确预测了观察到的标度区域。 我们的分析揭示了在没有热力学势的情况下相分离动力学中的意外复杂性。 显示英文摘要

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 scaling regime characterized by algebraic domain growth, at odds with the logarithmic coarsening of the standard voter model. A phenomenological approach based on cluster diffusion and similar to Smoluchowski ripening correctly predicts the observed scaling regime. Our analysis exposes unexpected complexity in the phase ordering dynamics without thermodynamic potential.
