Thin-shell wormholes supported by ordinary matter in Einstein--Gauss--Bonnet gravity
Martin Richarte, Claudio Simeone
TL;DR
This paper constructs thin-shell wormholes within Einstein--Gauss--Bonnet gravity, demonstrating that under specific conditions, they can be supported by matter satisfying standard energy conditions, unlike typical wormholes.
Contribution
It applies the generalized Darmois--Israel formalism to Einstein--Gauss--Bonnet theory to show wormholes supported by ordinary matter are possible.
Findings
Wormholes can be supported by matter satisfying energy conditions.
The formalism is extended to Einstein--Gauss--Bonnet gravity.
Parameter ranges allow for non-exotic matter support.
Abstract
The generalized Darmois--Israel formalism for Einstein--Gauss--Bonnet theory is applied to construct thin-shell Lorentzian wormholes with spherical symmetry. We calculate the energy localized on the shell, and we find that for certain values of the parameters wormholes could be supported by matter not violating the energy conditions.
