论文摘要
基于额外维度的紧凑型基本理论的最大挑战也许是适应一段加速的宇宙学扩展。先前的研究已经确定了两种压缩理论的黑暗能量存在的限制：（1）较高维图满足某些用于复制已知低能现象学的指标的限制；或（2）那些从字符串理论中得出的那些，假设它们满足了赃物的猜想。对于任何一个类别，分析表明，只有在采取精髓形式的情况下，黑暗能量才有可能。在本文中，我们探讨了属于阶级的理论的后果，并表明联合约束是高度限制的，几乎没有选择。
Perhaps the greatest challenge for fundamental theories based on compactification from extra dimensions is accommodating a period of accelerated cosmological expansion. Previous studies have identified constraints imposed by the existence of dark energy for two overlapping classes of compactified theories: (1) those in which the higher dimensional picture satisfies certain metric properties selected to reproduce known low energy phenomenology; or (2) those derived from string theory assuming they satisfy the Swampland conjectures. For either class, the analyses showed that dark energy is only possible if it takes the form of quintessence. In this paper, we explore the consequences for theories that belong to both classes and show that the joint constraints are highly restrictive, leaving few options.
