AdS真空泡的全息照相

Holography of AdS vacuum bubbles

Jose L. F. Barbon, Eliezer Rabinovici

摘要:

我们认为AdS真空的命运与隧道事件有关。在不稳定的CFT中,用Fubini瞬子提出了薄壁Coleman-de Luccia反弹的精确全息对偶。这一建议得到了几个定性和定量检查的支持,包括在评估衰变率时出现的瞬子作用的精确计算。大挤压表现为时间依赖的过程,在有限的时间内到达场空间的边界。所涉及的无穷大的能量差被确定的边界上,并突出了散装设置的不明确的性质。我们提出了一个定性的方案,其中的紧缩是解决稳定的CFT,使所有的尝试在紧缩总是最终屏蔽的边界形成的黑洞地平线。在所有这些定义良好的体过程中,组态具有相同的渐近性,并且是有限能量激发。

英文摘要:

We consider the fate of AdS vacua connected by tunneling events. A precise holographic dual of thin-walled Coleman--de Luccia bounces is proposed in terms of Fubini instantons in an unstable CFT. This proposal is backed by several qualitative and quantitative checks, including the precise calculation of the instanton action appearing in evaluating the decay rate. Big crunches manifest themselves as time dependent processes which reach the boundary of field space in a finite time. The infinite energy difference involved is identified on the boundary and highlights the ill-defined nature of the bulk setup. We propose a qualitative scenario in which the crunch is resolved by stabilizing the CFT, so that all attempts at crunching always end up shielded from the boundary by the formation of black hole horizons. In all these well defined bulk processes the configurations have the same asymptotics and are finite energy excitations.
