利用统计力学的概念，我们建立了一个通用的、自洽的理论框架，能够描述任何涉及守恒量的弱非线性光学多模系统。我们通过平衡状态下吉布斯熵的最大化推导出控制大正则系综的基本关系。在这幅经典的统计光力学图中，我们得到了概率分布、大配分函数和相关热力学势的解析表达式。我们的结果普遍适用于任何其他弱非线性多模玻色子系统。(C) 2020美国光学学会
By utilizing notions from statistical mechanics, we develop a general and self-consistent theoretical framework capable of describing any weakly nonlinear optical multimode system involving conserved quantities. We derive the fundamental relations that govern the grand canonical ensemble through maximization of the Gibbs entropy at equilibrium. In this classical picture of statistical photo-mechanics, we obtain analytical expressions for the probability distribution, the grand partition function, and the relevant thermodynamic potentials. Our results universally apply to any other weakly nonlinear multimode bosonic system. (C) 2020 Optical Society of America
