两个纠缠的CFTs的对偶是什么?

What is the dual of two entangled CFTs?

Samir D. Mathur

摘要:

证明了AdS中永恒黑洞的对偶是两个纠缠但不连通的CFTs。我们发现,霍金辐射的过程中产生的纠缠创造了这个猜想的几个挑战。而模糊球态的性质则暗示了一种不同的图景,即两个纠缠的CFTs的对偶是两个纠缠但不连通的时空。我们认为一个过程中的“快速隧道”的爱因斯坦-罗森桥的永恒的洞隧道迅速进入模糊球状态,防止存在的永恒的洞作为一个半经典时空。视界后面的区域则只出现在模糊球互补性的近似中,其中考虑了具有能量$E\gg T$的探针的影响。

英文摘要:

It has been conjectured that the dual of the eternal black hole in AdS is two entangled but disconnected CFTs. We show that the entanglement created by the process of Hawking radiation creates several challenges for this conjecture. The nature of fuzzball states suggests a different picture, where the dual to two entangled CFTs is two entangled but disconnected spacetimes. We argue for a process of `quick tunneling' where the Einstein-Rosen bridge of the eternal hole tunnels rapidly into fuzzball states, preventing the existence of the eternal hole as a semiclassical spacetime. The regions behind the horizon then emerge only in the approximation of fuzzball complementarity, where one considers the impact of probes with energy $E\gg T$.
