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…
Painlevé-Gullstrand coordinates discontinuity in the quantum Oppenheimer-Snyder model
Francesco Fazzini, Carlo Rovelli, Farshid Soltani
A metric that describes a collapsing star and the surrounding black hole geometry accounting for quantum gravity effects has been derived independently by different research groups…
Global Kruskal-Szekeres coordinates for Reissner-Nordström spacetime
Farshid Soltani
I derive a smooth and global Kruskal-Szekeres coordinate chart for the maximal extension of the non-extremal Reissner-Nordström geometry that provides a generalization to the stand…
On the geometry of the black-to-white hole transition within a single asymptotic region
Muxin Han, Carlo Rovelli, Farshid Soltani
We write explicitly the complete Lorentzian metric of a singularity-free spacetime where a black hole transitions into a white hole located in its same asymptotic region. In partic…
A spin foam framework for the black-to-white hole transition
Farshid Soltani
Black holes formation and evolution have been extensively studied at the classical level. However, not much is known regarding the end of their lives, a phase that requires to cons…
The End of a Black Hole's Evaporation -- Part II
Farshid Soltani, Carlo Rovelli, Pierre Martin-Dussaud
We derive an explicit expression for the transition amplitude from black to white hole horizon at the end of Hawking evaporation using covariant loop quantum gravity.
The End of a Black Hole's Evaporation -- Part I
Fabio D'Ambrosio, Marios Christodoulou, Pierre Martin-Dussaud +2
At the end of Hawking evaporation, the horizon of a black hole enters a physical region where quantum gravity cannot be neglected. The physics of this region has not been much expl…
