Static and Dynamic perturbations of scalar DBI analogue of a black hole
Pedro Meert, Horatiu Nastase
Perturbations around a spherically symmetric solution of the scalar Dirac-Born-Infeld (DBI) theory obey the equation of motion of a massless scalar field in a curved background wit…
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…
Rotational holographic transport from KN-AdS black hole
Pedro Meert, Horatiu Nastase
We consider rotational holographic transport in strongly coupled 2+1 dimensional systems, from the point of view of 3+1 dimensional gravity. We consider the moment of inertia a…
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…
Transport coefficients associated to black holes on the brane: analysis of the shear viscosity-to-entropy density ratio
Pedro Meert
In this thesis, we apply the AdS/CFT correspondence to space-times associated with extensions of General Relativity. We are particularly interested in calculating the transport coe…
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…
Gravitational decoupling, hairy black holes and conformal anomalies
Pedro Meert, Roldao da Rocha
Hairy black holes in the gravitational decoupling setup are studied from the perspective of conformal anomalies. Fluctuations of decoupled sources can be computed by measuring the…
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…
AdS-Schwarzschild deformed black branes and hydrodynamic transport coefficients
A. J. Ferreira-Martins, P. Meert, R. da Rocha
A family of deformed AdS-Schwarzschild black branes is here derived, employing the membrane paradigm of AdS/CFT. The solution of the Einstein-Hilbert action, with the Gibbons-H…
Deformed AdS4-Reissner-Nordström black branes and shear viscosity-to-entropy density ratio
A. J. Ferreira-Martins, P. Meert, R. da Rocha
A family of deformed AdS4-Reissner-Nordström black branes, governed by a free parameter, is derived using the ADM formalism, in the context of the membrane paradigm. Their new even…
The emergence of flagpole and flag-dipole fermions in fluid/gravity correspondence
P. Meert, R. da Rocha
The emergence of flagpole and flag-dipole singular spinor fields is explored, in the context of fermionic sectors of fluid/gravity correspondence, arising from the duality between…
