@article{BlzquezSalcedo2021TraversableWI, title={Traversable Wormholes in Einstein-Dirac-Maxwell Theory.}, author={Jose Luis Bl{\'a}zquez-Salcedo and Christian Knoll and Eugen Radu}, journal={Physical review letters}, year={2021}, volume={126 10}, pages={ 101102 } }

We construct a specific example of a class of traversable wormholes in Einstein-Dirac-Maxwell theory in four spacetime dimensions, without needing any form of exotic matter. Restricting to a model with two massive fermions in a singlet spinor state, we show the existence of spherically symmetric asymptotically flat configurations which are free of singularities, representing localized states. These solutions satisfy a generalized Smarr relation, being connected with the extremal Reissner…
