dS/CFT中的宇宙ER=EPR

Cosmic ER=EPR in dS/CFT

Jordan Cotler, Andrew Strominger

AI总结:

本文在dS/CFT对应中利用quasinormal mode基证明Euclidean真空是thermofield double态,揭示全局de Sitter几何从两个CFT副本的量子纠缠中涌现。

摘要:

在dS/CFT对应中,de Sitter时空全局类空切片上的体态对偶于(一般而言)对偶CFT Hilbert空间与其自身的张量积中的纠缠态。我们使用quasinormal mode基证明,Euclidean真空(对于一定质量范围内的自由标量)在对偶CFT描述中是thermofield double态,并且全局de Sitter几何从两个CFT副本之间的量子纠缠中涌现。对CFT的一个副本求迹会产生描述单一静态因果菱形的混合热态。

英文摘要:

In the dS/CFT correspondence, bulk states on global spacelike slices of de Sitter space are dual to (in general) entangled states in the tensor product of the dual CFT Hilbert space with itself. We show, using a quasinormal mode basis, that the Euclidean vacuum (for free scalars in a certain mass range) is a thermofield double state in the dual CFT description, and that the global de Sitter geometry emerges from quantum entanglement between two copies of the CFT. Tracing over one copy of the CFT produces a mixed thermal state describing a single static causal diamond.
