Traversable Thin-shell Wormhole in the 4D Einstein-Gauss-Bonnet Theory

Understand

This work investigates the spherically symmetric thin-shell wormhole solutions in four-dimensional Einstein-Gauss-Bonnet theory and explores their stabilities under radial, linear perturbations.

• These solutions are typically traversable and characterized by a thin-shell throat in accordance with Israel's junction conditions.
• In asymptotically flat and AdS spacetimes with a negative Gauss-Bonnet coupling constant, stable neutral wormholes are encountered when the magnitude of the coupling constant becomes significant.
• The throats of such wormholes are sustained by ordinary matter and possess finite radii.
