Starting from an effective action for quantum gravity, we calculate the quantum gravitational corrections to the Wald entropy of a four dimensional non-extremal Reissner–Nordström (RN) black hole in the limit of small electric charge, generalising a previous calculation carried out by Calmet and Kuipers (Phys Rev D 104(6):066012, 2021) for a Schwarzschild black hole. We show that, at second order in the Ricci curvature, the RN metric receives quantum corrections which shift the classical… 
Quantum Gravitational Corrections to the Geometry of Charged AdS Black Holes

Quantum corrections to the entropy of a Reissner-Nordström black hole due to spin fields
The quantum corrections to the entropy of the Reissner-Nordstr\"om black hole due to the gravitational, electromagnetic, and neutrino fields are calculated by using the brick-wall model. The
Quantum gravity of Kerr-Schild spacetimes and the logarithmic correction to Schwarzschild black hole entropy
A bstractIn the context of effective field theory, we consider quantum gravity with minimally coupled massless particles. Fixing the background geometry to be of the Kerr-Schild type, we fully

We calculate the quantum corrections of geometric and thermodynamic quantities for the Reissner-Nordstrom charged black hole, within the context of the two-dimensional spherically symmetric dilaton
Quantum gravitational corrections to a star metric and the black hole limit
In this paper we consider the full set of quantum gravitational corrections to a star metric to second order in curvature. As we use an effective field theoretical approach, these corrections apply
Entropy corrections for Schwarzschild and Reissner-Nordstrom black holes
A Schwarzschild black hole being thermodynamically unstable, corrections to its entropy due to small thermal fluctuations cannot be computed. However, a thermodynamically stable Schwarzschild
α′ corrections of Reissner-Nordström black holes
We study the first-order in α′ corrections to non-extremal 4-dimensional dyonic Reissner-Nordstrom (RN) black holes with equal electric and magnetic charges in the context of Heterotic Superstring

The treatment of gravity is described as a quantum effective field theory that allows a natural separation of the low energy quantum effects from the high energy contributions, and the leading quantum corrections to the gravitational interaction of two heavy masses are calculated.
Nonlocal quantum effects in cosmology: Quantum memory, nonlocal FLRW equations, and singularity avoidance
We discuss cosmological effects of the quantum loops of massless particles, which lead to temporal non-localities in the equations of motion governing the scale factor a(t). For the effects discussed
On the covariant formalism of the effective field theory of gravity and its cosmological implications
Following our previous work wherein the leading order effective action was computed in the covariant effective field theory of gravity, here we specialize the effective action to the FRW spacetime
