AI 中文摘要
我们证明,德西特/共形场论(dS/CFT)对应中,存在于未来和过去边界上的共形场理论(CFT)之间的量子纠缠,可通过威克转动到具有两个类时方向的几何结构来描述。我们提出了dS/CFT对应的一种新实现,其中该双时间几何上的量子引力与定义在洛伦兹环面上的CFT全息对偶。我们证明,这种对偶重现了dS全息图的关键特征,包括dS熵、关联函数和伪熵。最后,通过扩展路径积分优化框架,我们解释了dS时空如何从洛伦兹环面上的CFT中涌现。
英文摘要
We show that the quantum entanglement between the conformal field theories (CFTs) living on the future and past boundaries in the de Sitter/conformal field theory (dS/CFT) correspondence can be described by Wick rotating to a geometry with two timelike directions. We propose a new realization of the dS/CFT correspondence in which quantum gravity on this two-time geometry is holographically dual to a CFT defined on a Lorentzian torus. We show that this duality reproduces key features of dS holography, including the dS entropy, correlation functions, and pseudoentropy. Finally, by extending the framework of path-integral optimization, we explain how dS spacetime emerges from the CFT on the Lorentzian torus.
