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 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…
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…
Configurational entropy of black hole quantum cores
R. Casadio, R. da Rocha, P. Meert +2
Two types of information entropy are studied for the quantum states of a model for the matter core inside a black hole geometry. A detailed description is first given of the quantu…
Probing the minimal geometric deformation with trace and Weyl anomalies
P. Meert, R. da Rocha
The method of minimal geometric deformation (MGD) is used to derive static, strongly gravitating, spherically symmetric, compact stellar distributions. The trace and Weyl anomalies…
