本文给出了有限平均场伊辛系统中随机序参量松弛的模拟数据和理论分析。与无限平均场系统相反，有限平均场系统在性质上表现出与有限相互作用范围的系统相同的弛豫。他们探讨了平均场情况下不同版本的动力学伊辛模型的等效性，并研究了亚稳态的寿命。他们专注于附近的平均场旋节线，并提出了一个唯象的有限尺寸标度理论的寿命的亚稳态。
The authors present simulational data and a theoretical analysis of the stochastic order parameter relaxation in finite mean-field Ising systems. Contrary to infinite mean-field systems the finite ones exhibit qualitatively the same kind of relaxation as systems with finite interaction ranges. They explore the equivalence of different versions of the kinetic Ising model in the mean-field case and study the lifetime of metastable states. They focus on the vicinity of the mean-field spinodal and present a phenomenological finite-size-scaling theory for the lifetime of the metastable state.
