论文摘要
在本文中，我们研究了$ ads_4 $时空的商获得的时空。考虑了特定$ \ mathbb {z} _2 $的进一步商。在度量标准中占据一阶扰动，我们估计了物质领域在时空几何学上的反应。我们可以通过将其拉回覆盖空间来计算应力 - 能量张量的期望值。当选择合适的边界条件时，平均无效能量将变为负，从而导致可遍历的虫洞。
In this paper, we investigated the space-time obtained by quotients of the $AdS_4$ space-time. Further quotient with specific $\mathbb{Z}_2$ is considered. Taking up to the first-order perturbation in metric, we estimated the backreaction of the matter field on space-time geometry. We can calculate the stress-energy tensor's expected value by pulling it back onto the covering space. The average null energy becomes negative when the suitable boundary condition is chosen, resulting in a traversable wormhole.
