摘要:

在经典离散系统领域,特别是置换合金中,本研究引入了一种随机热力学方法来处理canonical ensemble中的非线性问题。该方法建立了多种体相互作用谱与相应平衡配置之间的非线性关系,通过canonical平均确定。所提出的方法通过新引入的热力学函数,促进了多个配置中的非线性分析。这些函数使配置空间中的非线性概念从局部扩展到统计流形中的非局部非线性。当前发现表明,部分有序与其它配置之间的平均非线性差异受理想线性系统中熵产的限制。该系统由配置空间中密度态的协方差矩阵全面描述。实际上,这种方法可能显著推进各种经典离散系统非线性分析的发展。

英文摘要:

In the field of classical discrete systems, specifically substitutional alloys, this study introduces a stochastic thermodynamic approach to address nonlinearity within a canonical ensemble. This approach establishes a nonlinear relationship between a spectrum of many-body interactions and the corresponding equilibrium configuration, as determined through the canonical average. The proposed method facilitates the analysis of nonlinearity across multiple configurations via newly introduced thermodynamic functions. These functions enable the formulation of nonlinearity in the configuration space, previously conceptualized as local, and extend it to nonlocal nonlinearity within statistical manifolds. The present findings indicate that the average nonlinearity disparity between partially ordered and other configurations is constrained by the entropy production in an ideal linear system. This system is comprehensively described by a covariance matrix of the density of states in the configuration space. Practically, this approach could significantly advance the analysis of nonlinearity for various classical discrete systems.
