Gauss-Bonnet modification to Hawking evaporation of AdS black holes in massive gravity
Hao Xu, Yun Du
The Stefan-Boltzmann law can estimate particle emission power and lifetime of a black hole. However, in modified gravity theories, new parameters in the action can cause qualitativ…
How Barrow Entropy Modifies Gravity: With Comments on Tsallis Entropy
Sofia Di Gennaro, Hao Xu, Yen Chin Ong
Barrow proposed that the area law of the horizon entropy might receive a "fractal correction" due to quantum gravitational effects, with $0\leqslant Δ\leqslant…
How Anti-de Sitter Black Holes Reach Thermal Equilibrium
Ru Ling, Hao Xu, Yen Chin Ong
It is commonly known in the literature that large black holes in anti-de Sitter spacetimes (with reflective boundary condition) are in thermal equilibrium with their Hawking radiat…
Black Hole Evaporation in Hořava-Lifshitz Gravity
Hao Xu, Yen Chin Ong
Hořava-Lifshitz (HL) gravity was formulated in hope of solving the non-renormalization problem in Einstein gravity and the ghost problem in higher derivative gravity theories by vi…
Cosmic Censorship and the Evolution of d-Dimensional Charged Evaporating Black Holes
Hao Xu, Yen Chin Ong, Man-Hong Yung
The cosmic censorship conjecture essentially states that naked singularities should not form from generic initial conditions. Since black hole parameters can change their values un…
Black hole evaporation in Lovelock gravity with diverse dimensions
Hao Xu, Man-Hong Yung
We investigate the black hole evaporation process in Lovelock gravity with diverse dimensions. By selecting the appropriate coefficients, the space-time solutions can possess a uni…
