Abstract

 

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, although not all the isometries

will remain realized globally. 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.
