A particular thin-shell wormhole

详细

Using a black hole with scalar hair, we construct a scalar thin-shell wormhole (TSW) in 2+1 dimensions by applying the Visser cut and paste technique. The surface stress, which is concentrated at the wormhole throat, is determined using the Darmois–Israel formalism. Using various gas models, we analyze the stability of the TSW. The stability region is changed by tuning the parameters l and u. We note that the obtained TSW originating from a black hole with scalar hair could be more stable with a particular value of the parameter l, but it still requires exotic matter.
