随机矩阵理论的节点

Knots from the random matrix theory with a replica

Shinobu Hikami

摘要:

一个经典的结被描述为一个一冲程的轨迹与纠缠的字符串。副本方法出现作为一个强大的工具,在统计力学的聚合物或自避免行走。我们认为这个副本N到0的限制在高斯平均的产品的N × N厄米矩阵,它提供了一个节点的一笔图的迹。节点和连杆的Seifert曲面由随机矩阵模型导出。利用Yang-Lee边奇异性的类比,讨论了单位圆上Alexander多项式的零点。本文讨论了Chern-Simons规范理论中的一个矩阵模型在高维纽结和半积分能级k下的推广。

英文摘要:

A classical knot is described by a one-stroke trajectory with entanglements of a string. The replica method appears as a powerful tool in statistical mechanics for a polymer or self-avoiding walk. We consider this replica N to 0 limit in Gaussian means of the products of trace of N x N Hermitian matrices, which provides one-stroke graphs of a knot. The Seifert surfaces of knots and links are derived by a random matrix model. The zeros of Alexander polynomials on a unit circle are discussed for the case of n-vertices in the analogy of Yang-Lee edge singularity. The extension of one matrix model is considered for higher dimensional knots and for half integral level k in Chern-Simons gauge theory.
