Super Yang-Mills理论中的单圈非平面反常维数

One-Loop Non-Planar Anomalous Dimensions in Super Yang-Mills Theory

Tristan McLoughlin, Raul Pereira, Anne Spiering

摘要:

本文研究了极大超对称Yang-Mills理论中的非平面单圈反常维数及其边缘形变类似物。利用Bethe状态的基础上,我们计算的扩张算子的矩阵元素,并找到紧凑的表达式在离壳标量积和六边形函数。然后,我们使用非简并量子力学微扰理论来计算领先的$1/N^2$的运营商尺寸的修正,并作为一个例子计算大$R$ -电荷限制的两个激发态通过subleading顺序在$R$ -电荷。最后,我们数值研究了这些理论的能级间距分布,并表明它们从无限$N$上可积系统的泊松分布过渡到有限$N$上量子混沌系统的GOE Wigner-Dyson分布。

英文摘要:

We consider non-planar one-loop anomalous dimensions in maximally supersymmetric Yang-Mills theory and its marginally deformed analogues. Using the basis of Bethe states, we compute matrix elements of the dilatation operator and find compact expressions in terms of off-shell scalar products and hexagon-like functions. We then use non-degenerate quantum-mechanical perturbation theory to compute the leading $1/N^2$ corrections to operator dimensions and as an example compute the large $R$-charge limit for two-excitation states through subleading order in the $R$-charge. Finally, we numerically study the distribution of level spacings for these theories and show that they transition from the Poisson distribution for integrable systems at infinite $N$ to the GOE Wigner-Dyson distribution for quantum chaotic systems at finite $N$.
