实空间重正化群中的组合变换

Combined Transformation for a Renormalization Group of Real Space

本文提出两种组合变换,对二维方格上的伊辛模型作了实空间重正化群变换,计算结果与精确结果相近。

T.wo combined transformations for the renormalization group of real space arede-scribed. Each of them consists of two transformations. The combined transformations are carried out for the Ising model at two-dimensional square lattice and the calculation results are y = 1.113, kc = 0.351 and Y= 1.290, kc = 0.300, respectively.
