High-Energy Scattering by Extreme Dilaton Black Holes
Takuya Maki, Kiyoshi Shiraishi
We investigate the high and low energy scattering of charged scalar waves from an extreme dilaton black hole (DBH). The analyses here correspond to forward scattering processes of…
Extremal Black Holes and Strings in Linear Dilaton Vacua
Takuya Maki, Kiyoshi Shiraishi
Analytic solutions to low-energy string theory, which describe arbitrary numbers of extreme `black holes (strings)' in linear dilaton vacua, are found.
Spontaneous Compactification of Bimetric Theory
Nahomi Kan, Takuya Maki, Kiyoshi Shiraishi
We propose a model of bimetric gravity in which the mixing of metrics naturally gives a mass to a graviton by the compactification with flux of two gauge fields in extra dimensions…
Magnetic Moment of Electrons near Cosmic Strings
Takuya Maki, Kiyoshi Shiraishi
We study the effect of background geometry generated by a thin cosmic string on the anomalous magnetic moment of the electron. We find that the magnitude of the quantum correction…
Moyal Quantization for Constrained System
Takayuki Hori, Takao Koikawa, Takuya Maki
We study the Moyal quantization for the constrained system. One of the purposes is to give a proper definition of the Wigner-Weyl(WW) correspondence, which connects the Weyl symbol…
Magnetic solutions to 2+1 dimensional gravity with dilaton field
Takao Koikawa, Takuya Maki, Atsushi Nakamula
We show a general method to solve 2+1 dimensional dilatonic Maxwell-Einstein equation with a positive or negative cosmological constant. All the physical solutions are listed with…
