PGI Virtual Seminar Series | Brianna Grado-White, Brandeis "Multi-mouth Traversable Wormholes"


Recently, several examples of traversable wormholes supported by well-controlled quantum effects and respecting reasonable energy conditions have been constructed. In this talk, I will describe a generalization of such solutions involving more than two mouths in the same asymptotic region. These wormholes may be traversed between any pair of mouths, are four-dimensional, and are asymptotically flat up to the presence of possible magnetic fluxes or cosmic strings that extend to infinity. I will also discuss implications for quantum entanglement in these systems.
