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…

Quantum dust cores of rotating black holes
Tommaso Bambagiotti, Roberto Casadio
Black holes are spacetimes that should describe the end state of the gravitational collapse of huge amounts of quantum matter. A quantum description of dust cores for black hole ge…

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…
