Z_N规范理论的相结构

PHASE STRUCTURE OF Z_6 LATTIOE GAUGE THEORY

用修正的Ｍｉｇｄａｌ—Ｋａｄａｎｏｆｆ递推关系讨论了Ｚ５格点规范理论的相结构，给出了该模型在全部耦合参数空间中的相变特征，得到的固定点和相图在数值上与ＭｏｎｔｅＣａｒｌｏ模似结果是一致的．

In the corrected Migdal-Kadanoff recurrence relations of lattice gauge systems,the phse structure for Z5 lattice gauge theory is discussed. The phase transition characters in whole coupling parameter space are obtained. It is found that the fixed point and the phse diagram obtained in this paper are numerically closer to that given by Monte Carlo simulation.
