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.

超对称可穿越虫洞

我们研究了纯规范 $N\!=\!2$ 超重力中的可穿越虫洞解，有和没有电磁场，在 $\mathrm{SO}(2,1)\!\times\!\mathrm{SO }(1,1)$。该模型允许 1/2-BPS 虫洞解决方案，其对应的全局定义的杀死旋量被呈现。一个非收缩循环可以通过压缩一个不影响剩余超对称性的坐标来获得，等距群现在是全局的 $\mathrm{SO}(2,1)\!\times\!\mathrm{SO}( 2)$。虫洞连接两个渐近的局部 $\mathrm{AdS}_4$ 区域，并取决于某些电荷和磁荷参数，并且隐含地取决于喉咙周围的紧凑坐标范围。我们提供了对时空边界的分析，并表明它可以断开或不断开，取决于指标中参数的值。最后，我们展示了这些时空如何避免拓扑审查定理。
