环形蜂窝二聚体模型中的Loop统计

Loop statistics in the toroidal honeycomb dimer model

Cédric Boutillier, Béatrice de Tilière

摘要:

嵌入在环面中的图上的二聚体模型可以被解释为随机自避免环的集合。本文考虑均匀环形蜂窝二聚体模型。我们证明了当图的网格趋于零且环面的方面固定时,回路集合的卷绕数按规律收敛于二维离散高斯分布。物理学家从他们对环形二维临界环模型的分析以及它们到环面上无质量自由场的映射中更普遍地知道这一点。本文包含了第一个数学证明,这个更一般的物理结果的特定情况下的环模型诱导的环形二聚体模型。

英文摘要:

The dimer model on a graph embedded in the torus can be interpreted as a collection of random self-avoiding loops. In this paper, we consider the uniform toroidal honeycomb dimer model. We prove that when the mesh of the graph tends to zero and the aspect of the torus is fixed, the winding number of the collection of loops converges in law to a two-dimensional discrete Gaussian distribution. This is known to physicists in more generality from their analysis of toroidal two-dimensional critical loop models and their mapping to the massless free field on the torus. This paper contains the first mathematical proof of this more general physics result in the specific case of the loop model induced by a toroidal dimer model.
