Signatures of loop quantum gravity in primordial black hole cosmologies
Antoine Dierckx, Sébastien Clesse, Francesca Vidotto
The possibility that Dark Matter (DM) is partially or totally constituted by stable Planckian remnants of light Primordial Black Holes (PBHs), suggested for instance by Loop Quantu…
Quasi-dust ekpyrotic scenario in Loop Quantum Cosmology
Emmanuel Frion, Mateo Pascual, Francesca Vidotto
In the framework of Loop Quantum Cosmology, we study a cosmological bouncing model with two fields that reproduce the desired features of the primordial power spectra. The model co…
Taming Thiemann's Hamiltonian constraint in canonical loop quantum gravity: reversibility, eigenstates and graph-change analysis
Thiago L. M. Guedes, Guillermo A. Mena Marugán, Markus Müller +1
The Hamiltonian constraint remains an elusive object in loop quantum gravity because its action on spinnetworks leads to changes in their corresponding graphs. As a result, calcula…
Computing the graph-changing dynamics of loop quantum gravity
Thiago L. M. Guedes, Guillermo A. Mena Marugán, Francesca Vidotto +1
In loop quantum gravity (LQG), states of the gravitational field are represented by labeled graphs called spin networks. Their dynamics can be described by a Hamiltonian constraint…
Thermodynamics without Time
Francesca Vidotto
Our fundamental theories, i.e., the quantum theory and general relativity, are invariant under time reversal. Only when we treat system from the point of view of thermodynamics, i.…
Planck stars, White Holes, Remnants and Planck-mass quasi-particles. The quantum gravity phase in black holes' evolution and its manifestations
Carlo Rovelli, Francesca Vidotto
This is a review of some recent developments on quantum gravity aspects of black hole physics. In particular, we focus on a scenario leading to the prediction of the existence of a…
