| contents | Traversable Wormholes with a Spontaneous Symmetry Breaking Scalar Field Soumya Chakrabarti Chiranjeeb Singha Fortschritte der Physik AbstractThe authors argue that a spherically symmetric traversable wormhole solution of the Einstein field equations can be supported by minimally coupled self‐interacting scalar field, which allows a spontaneous symmetry breaking of the field around the wormhole throat. Two cases are studied by the authors: (i) the phantom wormhole solution of Bronnikov and (ii) a generalized Kiselev wormhole. The property of radial null geodesics is studied by authors and the metric can describe either a two‐way or a one‐way traversable wormhole depending on certain parameter ranges are showed. The scalar field exhibits spontaneous symmetry breaking (SSB) within the coordinate range where a wormhole throat forms and helps one suggest that SSB may act as a threshold for wormhole throat formation. The authors also computed the radius of the photon sphere, the Lyapunov exponent, the shadow radius, and the innermost stable circular orbits for the geometries. 10.1002/prop.70013 http://onlinelibrary.wiley.com/termsAndConditions#vor |
