八面体方程的北极曲线

Arctic curves of the octahedron equation

P. Di Francesco, R. Soto-Garrido

摘要:

我们研究的八面体关系(也被称为$A_{\infty}$ $T$ -系统),特别是服从的配分函数的二聚体覆盖的阿兹特克钻石图。对于一类合适的双周期初始条件,我们找到了一个特别简单的因式分解形式的精确解。对于这些,我们表明,密度函数,测量的平均二聚体占领的一个面的阿兹特克图,服从一个系统的线性递归关系与周期系数。这使我们能够探索相应的二聚体模型的热力学极限,并推导出精确的“北极”曲线分离系统的各个阶段。

英文摘要:

We study the octahedron relation (also known as the $A_{\infty}$ $T$-system), obeyed in particular by the partition function for dimer coverings of the Aztec Diamond graph. For a suitable class of doubly periodic initial conditions, we find exact solutions with a particularly simple factorized form. For these, we show that the density function that measures the average dimer occupation of a face of the Aztec graph, obeys a system of linear recursion relations with periodic coefficients. This allows us to explore the thermodynamic limit of the corresponding dimer models and to derive exact "arctic" curves separating the various phases of the system.
