Mass (re)distribution for quantum dust cores of black holes
L. Gallerani, A. Mentrelli, A. Giusti +1
The collective ground state for a spherical symmetric dust ball has been investigated recently in [R. Casadio, Phys. Lett. B 843 (2023) 138055]. In this study, we refine that model…
Horizon quantum mechanics for coherent quantum black holes
Wenbin Feng, Andrea Giusti, Roberto Casadio
The formalism of the horizon quantum mechanics is applied to electrically neutral and spherically symmetric black hole geometries emerging from coherent quantum states of gravity t…
Quantum maximally symmetric space-times
Pedro Meert, Andrea Giusti, Roberto Casadio
We show that 4-dimensional maximally symmetric spacetimes can be obtained from a coherent state quantisation of gravity, always resulting in geometries that approach the Minkowski…
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…
