Quantum Improved Regular Kerr Black Holes
Chiang-Mei Chen, Yi Chen, Akihiro Ishibashi +1
We study the quantum improvement of Kerr black holes with mass-dependent scale identifications in asymptotically safe gravity. We find that a physically sensible identification can…
Flows of Rotating Extremal Attractor Black Holes
Norihiro Iizuka, Akihiro Ishibashi, Kengo Maeda
We investigate the attractor mechanism of five-dimensional extremal rotating black holes in Einstein gravity minimally coupled with a multiplet complex scalar. By imposing regulari…
Phase Structure of Quantum Improved Schwarzschild-(Anti)de Sitter Black Holes
Chiang-Mei Chen, Yi Chen, Akihiro Ishibashi +1
We study the phase structure of quantum improved Schwarzschild-(A)dS black holes in asymptotically safe gravity. Our results confirm some of the well-known properties of quantum bl…
Semiclassical Einstein equations from holography and boundary dynamics
Akihiro Ishibashi, Kengo Maeda, Takashi Okamura
In this paper, we consider how to formulate semiclassical problems in the context of the AdS/CFT correspondence, based on the proposal of Compere and Marolf. Our prescription invol…
A stationary black hole must be axisymmetric in effective field theory
Stefan Hollands, Akihiro Ishibashi, Harvey S. Reall
The black hole rigidity theorem asserts that a rotating stationary black hole must be axisymmetric. This theorem holds for General Relativity with suitable matter fields, in four o…
Flows of Extremal Attractor Black Holes
Norihiro Iizuka, Akihiro Ishibashi, Kengo Maeda
We study flows of non-supersymmetric attractor black holes in the context of gauge/gravity correspondence. As our bulk theory, we consider the Einstein-Maxwell-Dilaton system with…
