大N时二维SU(N)YM中威尔逊圈的本征值密度

Eigenvalue density of Wilson loops in 2D SU(N) YM at large N

Robert Lohmayer

摘要:

在二维欧氏SU(N)Yang-Mills理论中,与简单环相关联的威尔逊圈矩阵W的本征值密度在无穷N极限下经历了临界尺寸的相变. 1/det(z-W)和det(1+uW)/(1-vW)在有限N处的平均值导致两个不同的平滑表达式。鞍点分析表明,在无穷大N时,这两个函数都趋于已知的奇异结果。

英文摘要:

The eigenvalue density of a Wilson loop matrix W associated with a simple loop in two-dimensional Euclidean SU(N) Yang-Mills theory undergoes a phase transition at a critical size in the infinite-N limit. The averages of 1/det(z-W) and det(1+uW)/(1-vW) at finite N lead to two different smoothed out expressions. It is shown by a saddle-point analysis that both functions tend to the known singular result at infinite N.
