Is de Sitter space always excluded in semiclassical f(R) gravity?
Roberto Casadio, Andrea Giugno, Andrea Giusti +1
It is shown that the recent corpuscular description of gravity generically excludes de Sitter spacetime in any semiclassical version of f(R) gravity. A phantom phenomenology of the…
Quantum Formation of Primordial Black holes
R. Casadio, A. Giugno, A. Giusti +1
We provide a (simplified) quantum description of primordial black holes at the time of their formation. Specifically, we employ the horizon quantum mechanics to compute the probabi…
Domestic Corpuscular Inflaton
Andrea Giugno, Andrea Giusti
The aim of this paper is to provide a more precise description of the paradigm of corpuscular slow-roll inflation, which was previously introduced by Casadio et al. in [1]. Specifi…
Horizon Quantum mechanics: spherically symmetric and rotating sources
Roberto Casadio, Andrea Giugno, Andrea Giusti +1
The Horizon Quantum Mechanics is an approach that allows one to analyse the gravitational radius of spherically symmetric systems and compute the probability that a given quantum s…
Horizon quantum fuzziness for non-singular black holes
Andrea Giugno, Andrea Giusti, Alexis Helou
We study the extent of quantum gravitational effects in the internal region of non-singular, Hayward-like solutions of Einstein's field equations according to the formalism known a…
Quantum post-Newtonian theory for corpuscular Black Holes
Andrea Giugno
We discuss an effective theory for the quantum static gravitational potential in spherical symmetry up to the first post-Newtonian correction. We build a suitable Lagrangian from t…
