金刚石晶格上S4模型的相变
Phase transition of the S4 model on diamond lattice

应用实空间重整化群的方法，研究了金刚石晶格上S4模型的相变，求得了系统的临界点. 分析可知，本系统只存在Gauss不动点而无Wilson Fisher不动点，与金刚石晶格上的Gauss模型相比较，系统具有相同的临界点，表明它们属于同一个普适类.
According to the real space renormalization group method, the phase transition of S4 model on a diamond lattice is studied, and its critical points are obtained. The results show that there only exist a Gaussian fixed point and the Wilson-Fisher fixed point is not found. Compared to the Gauss model on a diamond lattice, they have the same critical points. The results indicate that the two systems belong to the same university class
