色Jackiw-Teitelboim引力的Schwarzian

Schwarzian for colored Jackiw-Teitelboim gravity

K. B. Alkalaev, Euihun Joung, Junggi Yoon

摘要:

本文研究了Jackiw-Teitelboim(JT)引力的着色形式的边界有效作用量。从色JT引力的$su(N,N)$ BF公式出发,导出了作为Schwarzian作用量的色推广的边界作用量.使用不同类型的$SU(N,N)$群分解的零温度和有限温度的情况下进行阐述。我们给出了边界作用量的半经典微扰分析,讨论了自旋1模的不稳定性及其对量子混沌的影响。彩虹AdS $_2$几何引入的颜色规范对称性自发破缺。

英文摘要:

We study the boundary effective action of the colored version of the Jackiw-Teitelboim (JT) gravity. We derive the boundary action, which is the color generalization of the Schwarzian action, from the $su(N,N)$ BF formulation of the colored JT gravity. Using different types of the $SU(N,N)$ group decompositions both the zero and finite temperature cases are elaborated. We provide the semi-classical perturbative analysis of the boundary action and discuss the instability of the spin-1 mode and its implication for the quantum chaos. A rainbow-AdS$_2$ geometry is introduced where the color gauge symmetry is spontaneously broken.
