论文摘要
在本文中,我们使用Karch-Randall Braneworld在二维(几乎)反DE保姆空间(ADS $ _2 $)中研究量子重力理论。我们专注于设置中的有效重力理论,其中两个Karch-Randall Branes嵌入了渐近广告中,形成了楔形。我们发现二维爱因斯坦 - 希尔伯特重力(或洛伦兹版本的马克斯菲尔德理论)的出现时,当麸皮很刚性时,但是当brane brane brane brane的张力被解释时。我们结果的一个特殊情况是Jackiw-Teitelboim(JT)重力,事实证明,该重力可用于解决量子重力的许多重要问题。我们工作的一个重要含义是,这些模型作为一维量子力学系统具有全息双重双重。最后,我们讨论了有关能源及其分辨率的难题。
In this paper, we use the Karch-Randall braneworld to study theories of quantum gravity in two dimensional (nearly) anti-de Sitter space (AdS$_2$). We focus on effective gravitational theories in the setup with two Karch-Randall branes embedded in an asymptotically AdS$_3$ bulk forming a wedge. We find the appearance of two-dimensional Einstein-Hilbert gravity (or the Lorenzian version of Marolf-Maxfield theory) when the branes are rigid but the emergence of a class of dilaton gravity models parameterized by the tensions of the two branes when brane fluctuations are accounted for. A special case of our result is Jackiw-Teitelboim (JT) gravity, which has been proven useful to address many important problems in quantum gravity. An important implication of our work is that these models have holographic duals as one-dimensional quantum mechanics systems. At the end, we discuss a puzzle regarding the energy spectrum and its resolution.
