| 摘 要： | 应用实空间重整化群的方法,研究了金刚石晶格上S~4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.

| Abstract: | 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. |
