角转移矩阵重整化群方法的级数展开:硬平方模型

Yao-ban Chan

摘要:

角转移矩阵重整化群方法是计算统计力学模型中物理量的一种有效方法。它起源于Baxter的角点传递矩阵方程和方法,由Nishino和Okunishi于1996年发展。在本文中,我们回顾和适应这种方法,以前用于数值计算,推导级数展开。我们用它来计算硬平方模型的配分函数的92项。我们还研究声称,该方法是次指数的数量产生的条款,并简要分析所产生的系列。

英文摘要:

The corner transfer matrix renormalization group method is an efficient method for evaluating physical quantities in statistical mechanical models. It originates from Baxter's corner transfer matrix equations and method, and was developed by Nishino and Okunishi in 1996. In this paper, we review and adapt this method, previously used for numerical calculations, to derive series expansions. We use this to calculate 92 terms of the partition function of the hard squares model. We also examine the claim that the method is subexponential in the number of generated terms and briefly analyse the resulting series.
