On the local term in the anomaly-induced action of Weyl quantum gravity
Andrei O. Barvinsky, Guilherme H. S. Camargo, Alexei E. Kalugin +2
The finite local conformally non-invariant -term emerges in the one-loop effective action of the model of quantum gravity based on the Weyl-squared classical action. This term…
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…
Wave Function Renormalization and Flow of Couplings in Asymptotically Safe Quantum Gravity
Hikaru Kawai, Nobuyoshi Ohta
The importance of the proper treatment of the wave function renormalization in the renormalization group analysis of quantum gravity is pointed out. The renormalization factor, som…
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…
One-loop divergences in higher-derivative gravity
Nobuyoshi Ohta
We give a review of the one-loop divergences in higher derivative gravity theories. We first make the bilinear expansion in the quantum fluctuation on arbitrary backgrounds, introd…
Running Newton Coupling, Scale Identification and Black Hole Thermodynamics
Chiang-Mei Chen, Yi Chen, Akihiro Ishibashi +2
We discuss the quantum improvement of black hole solutions in the context of asymptotic safety. The Newton coupling in this formulation depends on an energy scale, which must be id…
