Wormholes in Einstein-scalar-Gauss-Bonnet theories with a scalar self-interaction potential
arXiv:2006.13008 · doi:10.1103/PhysRevD.102.064010
Abstract
We construct wormholes in Einstein-scalar-Gauss-Bonnet theories with a potential for the scalar field that includes a mass term and self-interaction terms. By varying the Gauss-Bonnet coupling constant we delimit the domain of existence of wormholes in these theories. The presence of the self-interaction enlarges the domain of existence significantly. There arise wormholes with a single throat and wormholes with an equator and a double throat. We determine the physical properties of these wormholes including their mass, their size and their geometry.
