一个用于变分累积展开计算的MATHEMATICA软件包(VCE1.0)

A MATHEMATICA PACKAGE (VCE 1.0) TO USE FOR VARIATIONAL CUMULANT EXPANSION

摘要: 利用MATHEM ATICA软件包的符号运算功能,发展了一个在计算机上实现对含近邻相互作用的格点模型进行变分累积展开研究的程序包(VCE1.0)。高阶连接图的计数及自由能等的解析表达式都可用这个程序包直接得到。该程序包可用于一大类格点规范理论与统计物理模型的相结构的研究。

Abstract: Using symbolic capabilities of MATHEMATICA software,a package(VCE 1.0) is developed to use for variational cumulant expansion study in lattice models with neiboring interaction.Enumerating high order connected diagrams and analytical expansions of free energy and so on can be obtained by this package.This package can also be used to study some models of lattice gauge theory and statistical physics.
