二维重力场中的普适流动方程与混沌束缚饱和

Universal flow equations and chaos bound saturation in 2d dilaton gravity

Daniel Grumiller, Robert McNees

摘要:

我们表明,Jackiw-Teitelboim模型的几个功能,实际上是普遍的二维麦克斯韦-牛顿引力理论与广泛的渐近性质。这些理论满足一个流动方程的一个维度减少TTbar变形的结构,并表现出混沌行为的最大李雅普诺夫指数的信号。我们的结果的一个后果是一个不去定理的光滑流从渐近AdS 2区域的de Sitter不动点。

英文摘要:

We show that several features of the Jackiw-Teitelboim model are in fact universal properties of two-dimensional Maxwell-dilaton gravity theories with a broad class of asymptotics. These theories satisfy a flow equation with the structure of a dimensionally reduced TTbar deformation, and exhibit chaotic behavior signaled by a maximal Lyapunov exponent. One consequence of our results is a no-go theorem for smooth flows from an asymptotically AdS2 region to a de Sitter fixed point.
