关于Polyakov环的关联函数的注记

Remarks on correlators of Polyakov Loops

Herbert Neuberger

摘要:

在二维和四维SU(N)YM理论中研究了Polyakov圈本征值及其N依赖性。计算了二维YM中两个分离的Polyakov环的单本征值分布的连接关联函数,发现其结构与相应的埃尔米特随机矩阵系综的结构不同。没有大的$N$非解析性被发现的两个点功能的限制制度。建议的情况下,大N相变涉及Polyakov环路可能会发生。

英文摘要:

Polyakov loop eigenvalues and their N-dependence are studied in 2 and 4 dimensional SU(N) YM theory. The connected correlation function of the single eigenvalue distributions of two separated Polyakov loops in 2D YM is calculated and is found to have a structure differing from the one of corresponding hermitian random matrix ensembles. No large $N$ non-analyticities are found for two point functions in the confining regime. Suggestions are made for situations in which large-N phase transitions involving Polyakov loops might occur.
