AdS Black Hole Solution in Dilatonic Einstein-Gauss-Bonnet Gravity
Kei-ichi Maeda, Nobuyoshi Ohta, Yukinori Sasagawa
We find that AdS spacetime with a non-trivial linear dilaton field is an exact solution in the effective action of string theory, which is described by gravity with the Gauss-Bonne…
Dark Energy and QCD Ghost
Nobuyoshi Ohta
It has been suggested that the dark energy that explains the observed accelerating expansion of the universe may arise due to the contribution to the vacuum energy of the QCD ghost…
Cosmological intersecting brane solutions
Masato Minamitsuji, Nobuyoshi Ohta, Kunihito Uzawa
The recent discovery of an explicit dynamical description of p-branes makes it possible to investigate the existence of intersection of such objects. We generalize the solutions de…
Dynamical p-branes with a cosmological constant
Kei-ichi Maeda, Masato Minamitsuji, Nobuyoshi Ohta +1
We present a class of dynamical solutions in a D-dimensional gravitational theory coupled to a dilaton, a form field strength, and a cosmological constant. We find that for any D d…
Global Structure of Black Holes in String Theory with Gauss-Bonnet Correction in Various Dimensions
Nobuyoshi Ohta, Takashi Torii
We study global structures of black hole solutions in Einstein gravity with Gauss-Bonnet term coupled to dilaton in various dimensions. In particular we focus on the problem whethe…
Notes on Entropy Force in General Spherically Symmetric Spacetimes
Rong-Gen Cai, Li-Ming Cao, Nobuyoshi Ohta
In a recent paper [arXiv:1001.0785], Verlinde has shown that the Newton gravity appears as an entropy force. In this paper we show how gravity appears as entropy force in Einstein'…
