论文摘要
我们考虑了我们宇宙和假设的双胞胎反宇宙之间纠缠的观察性后果，在规范量子重力的第三个量化方案中。基于我们以前的研究，我们选择了某种特殊形式的互动相互作用，这使得宇宙对纠缠的熵可以在其经典演化的某些关键点上发散。我们发现，宇宙微波背景（CMB）功率谱的修改是由于与我们的双胞胎抗宇宙的纠缠所导致的小型模式$ k $ $ k $和小型多极数量$ l $放大了与planck约束在互动中的互动偶联到常量$λ_O\λ_o\ limssim \ mathcal \ natersim \ mathcal \ Mathcal \ Mathcal \ Mathcal {o}（o}（o} 10^10^^}）（56）。在观察到CMB和其他观察结果的背景下，还简要评论了一些其他允许更多关键点的耦合功能。
We consider observational consequences of the entanglement between our universe and a hypothetical twin anti-universe in the third quantization scheme of the canonical quantum gravity. Based on our previous investigations we select some special form of the interuniversal interaction which allows the entanglement entropy of the pair of universes to diverge at some critical points of their classical evolution. We find that the modification of the cosmic microwave background (CMB) power spectrum due to the entanglement with our twin anti-universe is enlarged for small modes $k$ and small multipole numbers $l$ with the Planck constraint onto the interaction coupling constant $λ_o\lesssim\mathcal{O}(10^{-56})$. Some other coupling functions which allow more critical points are also briefly commented on in the context of their observational effect on CMB and other observations.
