Thin-shell wormholes in dilaton gravity
Ernesto F. Eiroa, Claudio Simeone
TL;DR
This paper constructs charged thin-shell wormholes within dilaton gravity, analyzing the exotic matter needed and its dependence on model parameters, while ensuring energy conditions are met outside the shell.
Contribution
It introduces a method to build charged thin-shell wormholes in dilaton gravity with localized exotic matter and examines the energy conditions and matter dependence on parameters.
Findings
Exotic matter is localized in the shell.
Energy conditions are satisfied outside the shell.
The amount of exotic matter depends on model parameters.
Abstract
In this work we construct charged thin-shell Lorentzian wormholes in dilaton gravity. The exotic matter required for the construction is localized in the shell and the energy conditions are satisfied outside the shell. The total amount of exotic matter is calculated and its dependence with the parameters of the model is analysed.
