CDT meets Horava-Lifshitz gravity

J. Ambjorn, A. Gorlich, S. Jordan, J. Jurkiewicz, R. Loll

摘要:

因果动力学三角剖分理论(CDT)试图将量子引力的非微扰理论定义为时空几何的和。CDT框架的组成部分之一是全球时间叶理,它也在最近由Hoglava提出的量子引力理论中起着核心作用。我们表明,CDT的相图具有惊人的相似之处,通用Lifshitz相图呼吁由Hoclavava。我们认为,CDT可能提供一个统一的非微扰框架,各向异性以及各向同性的量子引力理论。

英文摘要:

The theory of causal dynamical triangulations (CDT) attempts to define a nonperturbative theory of quantum gravity as a sum over space-time geometries. One of the ingredients of the CDT framework is a global time foliation, which also plays a central role in the quantum gravity theory recently formulated by Hořava. We show that the phase diagram of CDT bears a striking resemblance with the generic Lifshitz phase diagram appealed to by Hořava. We argue that CDT might provide a unifying nonperturbative framework for anisotropic as well as isotropic theories of quantum gravity.
