Thermodynamics of Einstein-Gauss-Bonnet Black Holes and Ensemble-averaged Theory
Md Sabir Ali, C. Fairoos, C. L. Ahmed Rizwan +2
In this paper, using the ensemble-averaged theory, we define the thermodynamic free energy of Einstein-Gauss-Bonnet (EGB) black holes in anti-de Sitter (AdS) spacetime. This approa…

Black hole thermodynamics from an ensemble-averaged theory
Peng Cheng, Yu-Xiao Liu, Shao-Wen Wei
The path integral approach to a quantum theory of gravity is widely regarded as an indispensable strategy. However, determining what additional elements, beyond black hole or AdS s…
