论文摘要
时空如何在理论上有良好动机的多个抗DE保姆(ADS)真空中在景观中进行非扰动,一直是一个令人关注的问题。作为朝着这个问题迈出的一步,我们对ADS景观中不均匀宇宙进行了(3+1)D数值相对论模拟,并发现标量场的巨大不均匀性不仅可以发展成类似球体的气泡,还可以发展成新型的管子样结构。据观察,气泡或管壁(跨潜在的屏障)可能会作为准DS空间充气,而被墙壁分隔的不同区域在不同的ADS真空中,并且会朝着奇异性塌陷。
How the spacetime evolved non-perturbatively in a landscape with multiple anti-de Sitter (AdS) vacua, which is theoretically well-motivated, has always been a matter of concern. As a step towards this issue, we perform (3+1)D numerical relativity simulations for the inhomogeneous universe in an AdS landscape, and find that large inhomogeneity of scalar field can develop into not only sphere-like bubbles, but also novel tube-like structures. It is observed that the bubble or tube wall (across the potential barrier) likely inflates as a quasi-dS space, while the different regions separated by the walls are in different AdS vacua and will collapse towards singularity.
