广义伊辛模型的精确矩阵模型

Exact matrix model for generalized Ising model

Vadym Sakhno, Mykola Sakhno

摘要:

伊辛模型被推广到一个只通过共享自旋相互作用的细胞系统。细胞内存在各种复杂的相互作用,最简单的细胞内相互作用可归结为伊辛模型。该系统不仅可以是一维的,也可以是二维的,三维的,等等。本文的目的是开发一种方法来构建精确的矩阵模型,任何考虑系统中最简单的方式。没有这一点,几乎不可能分析复杂系统。在尝试了很多方法之后,这种方法已经简化为适合一年级学生。利用该方法构造了二维广义伊辛模型的精确矩阵模型。已经开发了以下方法来获得和分析配分函数和各种热力学函数。这些问题将在以后的文件中讨论。

英文摘要:

The Ising model was generalized to a system of cells interacting exclusively by presence of shared spins. Within the cells there are interactions of any complexity, the simplest intracell interactions come down to the Ising model. The system may be not only one-dimensional but also two-dimensional, three-dimensional, etc. The purpose of the paper is to develop an approach to constructing the exact matrix model for any considered system in the simplest way. Without this, it is almost impossible to analyze complex systems. After trying a lot of ways, the approach has been simplified to suit first year students. Using the approach, the exact matrix model for a two-dimensional generalized Ising model was constructed. The following approaches have already been developed to obtaining and analyzing partition function and various thermodynamic functions. They will be considered in following papers.
