S-branes from unbalanced black diholes
Kenji Sakamoto
We construct new non-singular and time-dependent solutions from the black diholes with unbalanced magnetic charge. These solutions are constructed by the double Wick rotation with…
Asymptotic States in Two Black Hole Moduli Space
Kenji Sakamoto
We discuss the quantum states in the moduli space, which constructed with maximally charged dilaton black holes. Considering the quantum mechanics in the moduli space, we obtain th…
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…
Non-topological soliton in three-dimensional supergravity
Yoshinori Cho, Kenji Sakamoto, Kiyoshi Shiraishi
We construct numerical solutions for non-topological solitons in three-dimensional U(1)-gauged supergravity. We find the region of the solutions showing with the BTZ m…
Quantum Scattering in Two Black Hole Moduli Space
Kenji Sakamoto, Kiyoshi Shiraishi
We discuss the quantum scattering process in the moduli space consisting of two maximally charged dilaton black holes. The black hole moduli space geometry has different structures…
Deconstructing Scalar QED at Zero and Finite Temperature
Nahomi Kan, Kenji Sakamoto, Kiyoshi Shiraishi
We calculate the effective potential for the WLPNGB in a world with a circular latticized extra dimension. The mass of the WLPNGB is calculated from the one-loop quantum effect of…
