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

Robert Lohmayer, Herbert Neuberger, Tilo Wettig

摘要:

1981年Durhuus和Olesen(DO)证明了在无穷大N时,在二维欧氏SU(N)Yang-Mills理论中,与一个简单回路相关联的威尔逊圈矩阵W的本征值密度在临界尺寸下经历相变。det(z-W)、1/det(z-W)和det(1+uW)/(1-vW)在有限N处的平均值导致三个不同的平滑表达式,它们都趋向于无穷N处的DO奇异结果。这些光滑的扩展,并相互比较。

英文摘要:

In 1981 Durhuus and Olesen (DO) showed that at infinite N 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. The averages of det(z-W), 1/det(z-W), and det(1+uW)/(1-vW) at finite N lead to three different smoothed out expressions, all tending to the DO singular result at infinite N. These smooth extensions are obtained and compared to each other.
