有限温度Z5 格点规范理论的相变结构(英文)
The Critical Structures of Z 5 Lattice Gauge Theory at Finite Temperature
【摘要】 利用改进的MK 重正化群方法,讨论了最高温度T = 1/a 下的Z5 格点规范理论的相变结构和温度耦合常数空间中的相变线,并计算了固定点的临界指数,所得结果支持SY 预言.
【Abstract】 In the scheme of the improved Migdal Kadanoff (MK) renormalization group transformation, the phase structure of Z 5 lattice gauge theory at the highest temperature of T =1/ a is discussed,the fundamental representations in the temperature coupling constant plan are obtained and the critical exponents are calculated.The results support the Svetitsky Yaffe (SY) predictions.
