陪集Wess-Zumino-Witten模型的多重Schramm-Loewner演化

Multiple Schramm-Loewner evolutions for coset Wess-Zumino-Witten models

Yoshiki Fukusumi

摘要:

我们制定了多个Schramm-Loewner演化(SLE)陪集Wess-Zumino-Witten(WZW)模型。所得的SLE可以描述多个界面的临界行为的二维统计力学模型,其临界性质是由陪集WZW模型分类。该系统的基本特征是李群流形上的多重布朗运动以及实轴上的多重布朗运动。通过对边界条件变化算子之间的关联函数施加鞅条件,明确地确定了布朗运动的漂移项,漂移项来自于界面的相互作用.作为一个具体的例子,我们在$Z(n)$亚费米子模型上建立了多重SLE方程,并计算了与3-SLE漂移项密切相关的交叉概率。

英文摘要:

We formulate multiple Schramm-Loewner evolutions (SLEs) for coset Wess-Zumino-Witten (WZW) models. The resultant SLEs may describe the critical behavior of multiple interfaces for the 2D statistical mechanics models whose critical properties are classified by coset WZW models. The SLEs are essentially characterized by multiple Brownian motions on a Lie group manifold as well as those on the real axis. The drift terms of the Brownian motions, which come from interactions of interfaces, are explicitly determined by imposing a martingale condition on correlation functions among boundary condition changing operators. As a concrete example, we formulate multiple SLE on the $Z(n)$ parafermion model and calculate the crossing probability which is closely related to 3-SLE drift terms.
