Singularity and differentiability at the origin of static and spherically symmetric black holes
Tommaso Antonelli, Marco Sebastianutti
The divergence of curvature invariants at a given point signals the impossibility of extending the spacetime to that point, with the derivative order of these diverging invariants…

Black Hole Solutions in Quantum Gravity with Vilkovisky-DeWitt Effective Action
Xavier Calmet, Andrea Giusti, Marco Sebastianutti
We study new black hole solutions in quantum gravity. We use the Vilkovisky-DeWitt unique effective action to obtain quantum gravitational corrections to Einstein's equations. In f…

Coherent electrically-charged quantum black holes
Tommaso Antonelli, Marco Sebastianutti, Andrea Giusti
We improve upon the results presented in [R. Casadio, et al., Phys. Rev. D 105 (2022) 124026] deriving a quantum-corrected Reissner-Nordström geometry containing an integrable sing…
