渗流模型中四个自旋的关联函数
Correlation function of four spins in the percolation model
摘要:
利用库仑气体技术计算了Potts模型在渗流$q\rightarrow 1$极限下的四自旋关联函数。已知四点函数定义特定模型的实际融合规则。在这方面,我们发现,融合的两个自旋,尺寸$Δ_σ=\frac{5}{96}$,产生一个新的通道,在4点函数,这是由于运营商的尺寸$Δ=5/8$。
英文摘要:
By using the Coulomb gas technics we calculate the four-spin correlation function in the percolation $q\rightarrow 1$ limit of the Potts model. It is known that the four-point functions define the actual fusion rules of a particular model. In this respect, we find that fusion of two spins, of dimension $Δ_σ=\frac{5}{96}$, produce a new channel, in the 4-point function, which is due to the operator with dimension $Δ=5/8$.
