Lessons from gauge fixing and polymerization of loop quantum black holes with a cosmological constant
Geeth Ongole, Parampreet Singh, Anzhong Wang
Loop quantization of Schwarzschild black holes with a cosmological constant for polymerization parameters which are constant is studied in the effective spacetime description. We s…
A new quantization scheme of black holes in effective loop quantum gravity
Wen-Cong Gan, Anzhong Wang
Loop quantum cosmology has achieved great successes, in which the polymerization plays a crucial role. In particular, the phase-space-variable dependent polymerization turns out to…
Quasi-Normal Modes of Loop Quantum Black Holes Formed from Gravitational Collapse
Chao Zhang, Anzhong Wang
In this paper, we study the quasi-normal modes (QNMs) of a scalar field in the background of a large class of quantum black holes that can be formed from gravitational collapse of…
Even- and odd-parity stabilities of black holes in Einstein-Aether gravity
Antonio De Felice, Shinji Mukohyama, Shinji Tsujikawa +2
In Einstein-Aether theories with a timelike unit vector field, we study the linear stability of static and spherically symmetric black holes against both even- and odd-parity pertu…
Revisiting linear stability of black hole odd-parity perturbations in Einstein-Aether gravity
Shinji Mukohyama, Shinji Tsujikawa, Anzhong Wang
In Einstein-Aether gravity, we revisit the issue of linear stabilities of black holes against odd-parity perturbations on a static and spherically symmetric background. In this the…
