大N_c约束与turbulence

Large N_c confinement and turbulence

Jean-Paul Blaizot, Maciej A. Nowak

摘要:

我们认为,过渡发生在大$N_c$的本征值分布的威尔逊圈可能有一个湍流的起源。我们得出这一结论,通过研究复值无粘Burgers-Hopf方程,对应的马氏-Migdal回路方程,我们证明了出现的冲击波的频谱流的威尔逊圈特征值。这幅图补充了杜尔胡斯-奥勒森转变的图景,特别体现了无序。激波形成时的临界行为使我们能够推断出纳拉亚南和纽伯格最近在$d=2$和$d=3$的晶格模拟中测量到的指数。我们的分析使我们推测,在这些晶格模拟中观察到的普遍行为可能是禁闭的一般特征,也在$d=4$ Yang-Mills理论。

英文摘要:

We suggest that the transition that occurs at large $N_c$ in the eigenvalue distribution of a Wilson loop may have a turbulent origin. We arrived at this conclusion by studying the complex-valued inviscid Burgers-Hopf equation that corresponds to the Makeenko-Migdal loop equation, and we demonstrate the appearance of a shock in the spectral flow of the Wilson loop eigenvalues. This picture supplements that of the Durhuus-Olesen transition with a particular realization of disorder. The critical behavior at the formation of the shock allows us to infer exponents that have been measured recently in lattice simulations by Narayanan and Neuberger in $d=2$ and $d=3$. Our analysis leads us to speculate that the universal behavior observed in these lattice simulations might be a generic feature of confinement, also in $d=4$ Yang-Mills theory.
