论文摘要
局部平衡热力学是对汉密尔顿系统的均衡动力学的宏观描述的基本假设。我们在二维中分析了哈密顿potts模型，以研究对热传导中相共存的假设的侵犯。我们观察到，有序状态和无序状态之间的界面温度偏离了平衡过渡温度，表明平衡处的亚稳态状态通过热通量的影响稳定。我们还发现，在热力学的扩展框架中提出的公式描述了偏差。
The local equilibrium thermodynamics is a basic assumption of macroscopic descriptions of the out of equilibrium dynamics for Hamiltonian systems. We numerically analyze the Hamiltonian Potts model in two dimensions to study the violation of the assumption for phase coexistence in heat conduction. We observe that the temperature of the interface between ordered and disordered states deviates from the equilibrium transition temperature, indicating that metastable states at equilibrium are stabilized by the influence of a heat flux. We also find that the deviation is described by the formula proposed in an extended framework of the thermodynamics.
