Wormhole metric
Masato Nozawa, Takashi Torii
The C-metric in vacuum general relativity describes a pair of accelerated black holes supported by conical singularity. In this paper, we present a new family of exact solutions to…
New family of C-metrics in gauged supergravity
Masato Nozawa, Takashi Torii
We present a new family of charged C-metrics in gauged supergravity in four dimensions. The double Wick rotation of the C-metric allows us to bring our solution into a…
Nonlinear Dynamics in the Einstein-Gauss-Bonnet gravity
Hisa-aki Shinkai, Takashi Torii
We numerically investigated how the nonlinear dynamics depends on the dimensionality and on the higher-order curvature corrections in the form of Gauss-Bonnet (GB) terms. We especi…
Wormholes in higher dimensional space-time: Exact solutions and their linear stability analysis
Takashi Torii, Hisa-aki Shinkai
We derive the simplest traversable wormhole solutions in -dimensional general relativity, assuming static and spherically symmetric spacetime with a ghost scalar field. This is…
Asymptotically AdS Charged Black Holes in String Theory with Gauss-Bonnet Correction in Various Dimensions
Nobuyoshi Ohta, Takashi Torii
We study charged black hole solutions in Einstein-Maxwell-Gauss-Bonnet theory with the dilaton field which is the low-energy effective theory of the heterotic string. The spacetime…

Nobuyoshi Ohta, Takashi Torii
We study charged black hole solutions in Einstein-Gauss-Bonnet theory with the dilaton field which is the low-energy effective theory of the heterotic string. The spacetime is D-di…
