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 conformal field theories (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.

从全息虫洞加速宇宙学

我们考虑宇宙学模型，其中宇宙学通过分析延拓与欧几里得渐近 AdS 平面虫洞几何相关，通过一对三维欧几里得共形场论 (CFT) 全息定义。我们认为，由于 CFT 中与相关标量算子相关的标量场的势能，这些模型通常可以引起宇宙学的加速阶段。我们解释了宇宙学可观测量如何与虫洞时空中的可观测量相关联，并认为这导致了宇宙学自然性难题的新视角。
