论文摘要
我们表明，在Jackiw-teitelboim（JT）重力中，延迟两点功能可以从时空中获得带有Mobius带（带有一个crosscap的磁盘）的时空贡献的领先贡献。这种贡献与标准“高原”之间存在一个有趣的相互作用。根据拓扑加权因素，两者可以加在一起或取消。我们将这种行为与随机矩阵理论（RMT）和Sachdev-Kitaev-ye（SYK）结果的N Mod 8周期性相匹配。
We show that in Jackiw-Teitelboim (JT) gravity, late-time two-point functions can get a leading non-decaying contribution from a spacetime with the topology of a Mobius strip (a disk with one crosscap). There is an interesting interplay between this contribution and the standard "plateau". The two can add together or cancel, depending on topological weighting factors. We match this behavior to Random Matrix Theory (RMT) and the N mod 8 periodicity of Sachdev-Kitaev-Ye (SYK) results.
