二维临界点的离散全纯性

Discrete Holomorphicity at Two-Dimensional Critical Points

John Cardy

摘要:

在简要回顾了解析性在临界现象研究中的历史作用之后,本文介绍了临界二维格点模型中离散全纯观测量的最新发现。这些物体的关联函数满足离散形式的柯西-黎曼关系。它们的存在似乎与模型的可积性有很深的关系,它们可能是出现在描述连续极限的共形场论(CFT)中的真正全纯观测量的晶格版本。这个假设揭示了CFT和可积性之间的联系,如果得到验证,也可以用来证明这些模型中某些离散曲线的标度极限是由Schramm-Loewner演化(SLE)描述的。

英文摘要:

After a brief review of the historical role of analyticity in the study of critical phenomena, an account is given of recent discoveries of discretely holomorphic observables in critical two-dimensional lattice models. These are objects whose correlation functions satisfy a discrete version of the Cauchy-Riemann relations. Their existence appears to have a deep relation with the integrability of the model, and they are presumably the lattice versions of the truly holomorphic observables appearing in the conformal field theory (CFT) describing the continuum limit. This hypothesis sheds light on the connection between CFT and integrability, and, if verified, can also be used to prove that the scaling limit of certain discrete curves in these models is described by Schramm-Loewner evolution (SLE).
