Extremalization approach to black hole thermodynamics: perturbations around higher-derivative gravities
Aonan Zhang, Qiang Wang, Yong Xiao
When higher-derivative terms are added to a gravitational action, black hole solutions and their thermodynamic properties are generally corrected. Recent progress has shown that, b…
Validity of the Background Subtraction Method for Black Hole Thermodynamics in Matter-Coupled Gravity Theories
Yong Xiao, Aonan Zhang
The background subtraction method has long served as a practical tool for computing the Euclidean action and thermodynamic quantities of black holes. While its equivalence to the I…
A universal relation among Euclidean integrals for black holes in higher-derivative gravity theories
Yong Xiao, Qiang Wang, Aonan Zhang
In this paper, we establish a universal equality governing Euclidean integrals of gravitational actions in higher-derivative theories. This relation is shown to hold universally fo…
Quantum gravitational corrections to Reissner-Nordström black hole thermodynamics and their implications for the weak gravity conjecture
Yong Xiao, Qiang Wang, Aonan Zhang
In this paper, we investigate the quantum gravitational corrections to the thermodynamical quantities of Reissner-Nordström black holes within the framework of effective field theo…
