论文摘要
我们研究了纯尺寸的$ n \！= \！2 $的可穿越的虫洞解决方案，带有和不带电磁场，这些磁场是$ \ mathrm {so}（so}（2,1）（2,1）\！\ times \！\！\！\！\！\ mathrm {so so}（1,1,1）$下的本地等距。该模型允许提供1/2-BPS虫洞溶液，其相应的全球定义杀戮旋转器被呈现。可以通过压实留下残留超对称性不受影响的坐标之一来获得一个不可裁定的循环，等轴测组现在是全球$ \ mathrm {so}（so}（2,1）\！\！\！\！\！\！\！\！\！虫洞连接两个渐近，本地$ \ mathrm {ads} _4 $区域，并依赖于某些电和磁电荷参数，并隐含地在喉咙周围紧凑型坐标的范围内。我们提供了时空边界的分析，并表明它可以断开或不连接，具体取决于度量中的参数值。最后，我们展示了这些空间时间如何避免拓扑审查定理。
We study traversable wormhole solutions in pure gauged $N\!=\!2$ supergravity with and without electromagnetic fields, which are locally isometric under $\mathrm{SO}(2,1)\!\times\!\mathrm{SO}(1,1)$. The model allows for 1/2-BPS wormhole solutions whose corresponding globally defined Killing spinors are presented. A non-contractible cycle can be obtained by compactifying one of the coordinates which leaves the residual supersymmetry unaffected, the isometry group is now globally $\mathrm{SO}(2,1)\!\times\!\mathrm{SO}(2)$. The wormholes connect two asymptotic, locally $\mathrm{AdS}_4$ regions and depend on certain electric and magnetic charge parameters and, implicitly, on the range of the compact coordinate around the throat. We provide an analysis of the boundary of the spacetime and show that it can be either disconnected or not, depending on the values of the parameters in the metric. Finally, we show how that these space-times avoid a topological censorship theorem.
