Quantum Effects near Charged Dilatonic Black Holes
Kiyoshi Shiraishi
The expectation value in the Hartle-Hawking vacuum is calculated for minimally-coupled neutral scalar fields at the horizon of a charged dilatonic black hole.

Superradiance from a Charged Dilaton Black Hole
Kiyoshi Shiraishi
We study the behavior of the wave function of charged Klein-Gordon field around a charge dilaton black hole. The rate of spontaneous charge loss is estimated for large black hole c…

Quantum Corrections to Entropy of Charged Dilatonic Black Holes in Arbitrary Dimensions
Kiyoshi Shiraishi
The quantum contribution of a scalar field to entropy of a dilatonic black hole is calculated in the brick wall model by the WKB method and analyzed by a high-temperature expansion…
