临界伊辛模型中一次场的关联

Correlations of primary fields in the critical Ising model

Dmitry Chelkak, Clément Hongler, Konstantin Izyurov

摘要:

我们证明了初等场的重整化关联的收敛性,即。即,自旋、无序、费米子和能量密度,在任意非连通域中的临界伊辛模型的标度极限中,具有固定(正或负)或自由边界条件,或其混合。我们描述的限制的相关性的解决方案的黎曼边值问题,并证明其共形协方差。此外,我们证明了融合规则,或算子乘积展开,它描述了渐近的相关性的缩放限制的一些点碰撞在一起。在单连通域和双连通域的情况下,我们给出了相关性的显式公式。我们的演示文稿是独立的,和证明被简化相比,以前的工作,在特定的情况下进行治疗。

英文摘要:

We prove convergence of renormalized correlations of primary fields, i. e., spins, disorders, fermions and energy densities, in the scaling limit of the critical Ising model in arbitrary finitely connected domains, with fixed (plus or minus) or free boundary conditions, or mixture thereof. We describe the limits of correlations in terms of solutions of Riemann boundary value problems, and prove their conformal covariance. Moreover, we prove fusion rules, or operator product expansions, which describe asymptotics of the scaling limits of the correlations as some of the points collide together. We give explicit formulae for correlations in the case of simply-connected and doubly-connected domains. Our presentation is self-contained, and the proofs are simplified as compared to the previous work where particular cases are treated.
