AN IMPROVEMENT IN SELF-CONSISTENT CLUSTER METHOD FOR DETERMINING THE CRITICAL POINT IN ISING SPIN SYSTEM
对确定Ising自旋系统临界点自洽集团方法的改进

We show the equivalence between the self-consistent cluster method (SCM) and the modified cluster field method (MCFM). Based on the SCM and MCFM, we propose a new method to- calculate critical points of Ising spin system, the method is demonstrated on the two-dimension square lattice.
