Quantum aspects of self-interacting fields around cosmic strings
Kiyoshi Shiraishi, Satoru Hirenzaki
The authors study the quantum effect of self-interacting fields in the classical background of conical space, i.e. around a cosmic string with infinitesimal width. The renormalized…
Charged black holes in a six-dimensional vector-tensor theory
Kiyoshi Shiraishi
We study a six-dimensional vector-tensor gravitation theory compactified to M_4 x S^2. Here, static spherically-symmetric solutions to the field equations of the theory are investi…
Quantum fluctuation of stress tensor and black holes in three dimensions
Kiyoshi Shiraishi, Takuya Maki
The quantum stress tensor near a three-dimensional black hole is studied for a conformally coupled scalar field. The back reaction to the metric is also investigated.
Three-dimensional black holes and solitons in higher-dimensional theories with compactification
Takuya Maki, Kiyoshi Shiraishi
Several types of static solutions to Einstein's equations coupled with antisymmetric tensor fields are found in -dimensional spacetime. The solutions describe a product of…
