Thin-shell wormholes in 2+1-dimensional Einstein-Scalar Theory
arXiv:1702.06021 · doi:10.1142/S021773231750064X
Abstract
We present an infinite class of one-parameter scalar field extensions to the BTZ black hole in 2+1-dimensions. By virtue of the scalar charge the thin-shell wormhole supported by a linear fluid at the throat becomes stable against linear perturbations. More interestingly, we provide an example of thin-shell wormhole which is strictly stable in the sense that it is confined in between two classically intransmissible potential barriers.
