论文摘要
我们将可遍历的双面虫洞的Gao-Jafferis壁构造为多边界虫洞。在我们的构造中，我们将背景时空作为广告中的多边界黑洞$ _3 $。我们在热线限制下工作，在某些地区的双重CFT状态与热菲尔德双状态相似。此外，在这些区域中，热限制使因果阴影成倍小。基于热极限的这两个特征，并以三势虫洞作为我们的主要示例，我们表明，可以使用双迹线变形触发多支球孔中任何两个渐近区域之间的遍历性。特别是，两个边界区域不需要具有相同的温度和角动量。我们讨论了遍及术中遍历性的非平凡角度依赖性以及因果阴影区域的影响。
We generalize the Gao-Jafferis-Wall construction of traversable two-sided wormholes to multi-boundary wormholes. In our construction, we take the background spacetime to be multi-boundary black holes in AdS$_3$. We work in the hot limit where the dual CFT state in certain regions locally resembles the thermofield double state. Furthermore, in these regions, the hot limit makes the causal shadow exponentially small. Based on these two features of the hot limit, and with the three-boundary wormhole as our main example, we show that traversability between any two asymptotic regions in a multi-boundary wormhole can be triggered using a double-trace deformation. In particular, the two boundary regions need not have the same temperature and angular momentum. We discuss the non-trivial angular dependence of traversability in our construction, as well as the effect of the causal shadow region.
