One-loop finite potential for N-2 scalars from N quantum fields
Yoshinori Cho, Nahomi Kan, Kenji Sakamoto +1
We study the one-loop effective potential induced from quantum fluctuation of a finite number of fields. A series expansion in terms of the modified Bessel functions is useful to e…

Scattering in Two Black Hole Moduli Space
Kenji Sakamoto, Kiyoshi Shiraishi
In this work, we discuss the quantum mechanics on the moduli space consisting of two maximally charged dilaton black holes. We study the quantum effects resulting from the differen…

Black Holes with Scalar Hair in (2+1) dimensions
Yoshitaka Degura, Kenji Sakamoto, Kiyoshi Shiraishi
Nonrotating and rotating black hole soltuions in (2+1) dimensions are studied in a model including a real scalar field with a simple potential coupled to gravity.
