A loop quantization of the marginally bound Lemaître-Tolman-Bondi dust model
Luca Cafaro, Farshid Soltani
We present a loop quantization of the marginally bound Lemaître-Tolman-Bondi (LTB) model, describing the gravitational collapse of pressureless dust in spherical symmetry. The full…

Stellar collapse with pressure in effective loop quantum gravity
Luca Cafaro, Lorenzo Cipriani, Francesco Fazzini +1
We explore semiclassical stellar collapse scenarios with pressure within the framework of effective loop quantum gravity. The objective of this work is to generalize existent model…

Status of Birkhoff's theorem in polymerized semiclassical regime of Loop Quantum Gravity
Luca Cafaro, Jerzy Lewandowski
The collapse of a spherically symmetric ball of dust has been intensively studied in Loop Quantum Gravity (LQG). From a quantum theory, it is possible to recover a semiclassical re…
