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…

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 sin…

Quasinormal modes for coherent quantum black holes
Tommaso Antonelli, Andrea Giusti, Roberto Casadio +1
Coherent quantum black holes are quantum geometries obtained by means of a mean-field-like approach to the gravitational interaction. This procedure attenuates the classical spacet…
