Addendum to "thin-shell wormholes supported by ordinary matter in Einstein-Gauss-Bonnet gravity"
(American Physical Society, 2011-04)
Thin-shell wormholes are constructed starting from the exotic branch of the Wiltshire spherically symmetric solution of Einstein-Gauss-Bonnet gravity. The energy-momentum tensor of the shell is studied, and it is shown ...
Superradiance of charged black holes in Einstein-Gauss-Bonnet gravity
(IOP Publishing, 2018-04)
In this paper we show that electrically charged black holes in Einstein-Gauss-Bonnet gravity suffer from a superradiant instability. It is triggered by a charged scalar field that fulfils Dirichlet boundary conditions at ...
General aspects of Gauss-Bonnet models without potential in dimension four
(IOP Publishing, 2017-07)
In the present work, the isotropic and homogenous solutions with spatial curvature k=0 of four dimensional Gauss-Bonnet models are characterized. The main assumption is that the scalar field φ which is coupled to the ...
