六顶点模型的边界关联函数

Boundary correlation functions of the six-vertex model

N. M. Bogoliubov, A. G. Pronko, M. B. Zvonarev

摘要:

我们考虑了具有畴壁边界条件的$N \times N$正方晶格上的六顶点模型。模型的边界单点关联函数表示为$N\times N$矩阵的行列式,推广了配分函数的已知结果。在自由费米子的情况下,得到明确的答案。引入的关联函数与交替符号矩阵和多米诺骨牌的计数问题密切相关。

英文摘要:

We consider the six-vertex model on an $N \times N$ square lattice with the domain wall boundary conditions. Boundary one-point correlation functions of the model are expressed as determinants of $N\times N$ matrices, generalizing the known result for the partition function. In the free fermion case the explicit answers are obtained. The introduced correlation functions are closely related to the problem of enumeration of alternating sign matrices and domino tilings.
