Coherent quantum geometry: de Sitter spacetime in different foliations
Tommaso Bambagiotti, Roberto Casadio, Andrea Giusti +1
In any theory of quantum gravity, an interesting question to address is to what extent known solutions of the Einstein field equations can be obtained as expectation values of metr…
On gravitational collapse and integrable singularities
Roberto Casadio, Andrea Giusti, Alexander Kamenshchik +1
Schwarzschild black holes are expected to emerge as the end states of the classical gravitational collapse from non-singular configurations. After integrable curvature singularitie…
Probing Cosmic Expansion and Early Universe with Einstein Telescope
Angelo Ricciardone, Mairi Sakellariadou, Archisman Ghosh +52
Over the next two decades, gravitational-wave (GW) observations are expected to evolve from a discovery-driven endeavour into a precision tool for astrophysics, cosmology, and fund…
Quantum dust cores of black holes and their quasi-normal modes
Tommaso Bambagiotti, Luca Gallerani, Andrea Mentrelli +2
The quantum description of a gravitationally collapsed ball of dust proposed in Ref.~\cite{Casadio:2023ymt} is characterised by a linear effective Misner-Sharp-Hernandez mass funct…
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…
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…
Black Holes with a charged quantum dust core
R. Casadio, R. da Rocha, A. Giusti +1
To understand the nature of the black holes that exist in the Universe, it is also necessary to study what happens to the (quantum) matter that collapses and forms such objects. In…
Thermodynamic and configurational entropy of quantum Schwarzschild geometries
R. Casadio, R. da Rocha, A. Giusti +1
We study different entropies for coherent states representing the geometry of spherically symmetric compact systems. We show that the thermodynamic entropy reproduces the Bekenstei…
