摘要翻译:
二维伊辛模型的普适性等级,甚至跃迁的顺序,取决于相互作用的范围和对称性(Onsager模型、Baxter-Wu模型、Turban模型等),但由于自对偶性,临界温度一般是相同的。本文考虑相互作用形式的突变,研究了最近邻模型的非平衡临界动力学性质。磁化强度的弛豫和自相关函数的衰减表现出幂律行为,特征指数依赖于初态的普适性类别。

英文摘要:
  The universality class, even the order of the transition, of the two-dimensional Ising model depends on the range and the symmetry of the interactions (Onsager model, Baxter-Wu model, Turban model, etc.), but the critical temperature is generally the same due to self-duality. Here we consider a sudden change in the form of the interaction and study the nonequilibrium critical dynamical properties of the nearest-neighbor model. The relaxation of the magnetization and the decay of the autocorrelation function are found to display a power law behavior with characteristic exponents that depend on the universality class of the initial state.
