    Quantum gravitational corrections to the geometry of charged AdS black holes by Behnam Pourhassan, Ruben Campos Delgado, Sudhaker Upadhyay, Hoda Farahani, Himanshu Kumar

    Published 2025-03-01
    “…By employing the effective field theory framework for quantum gravity, we compute quantum corrections to the entropy of charged AdS black holes, focusing on second-order curvature terms. By incorporating scale-dependent coefficients, we establish that the Wald entropy is renormalization group (RG) invariant, confirming the robustness of the framework. …”
