论文摘要
我们考虑了宇宙学通过分析延续与桉树徒的渐近造型相关的宇宙学模型,该模型通过一对三维欧几里得CFT逐渐定义了全息定义。我们认为,由于与CFT中相关标量运算符相关的标量场的势能,这些模型通常会引起宇宙学的加速阶段。我们解释了宇宙学可观察到与虫洞时空中可观察物的关系,并认为这导致了宇宙学中自然难题的新观点。
We consider cosmological models in which the cosmology is related via analytic continuation to a Euclidean asymptotically AdS planar wormhole geometry defined holographically via a pair of three-dimensional Euclidean CFTs. We argue that these models can generically give rise to an accelerating phase for the cosmology due to the potential energy of scalar fields associated with relevant scalar operators in the CFT. We explain how cosmological observables are related to observables in the wormhole spacetime and argue that this leads to a novel perspective on naturalness puzzles in cosmology.
