Report on the session Loop Quantum Gravity: Cosmology and Black Holes of the 16th Marcel Grossmann Meeting
Jorge Pullin, Parampreet Singh
We summarize the main results of 19 talks presented at the QG3 session (loop quantum gravity: cosmology and black holes) of the 16th Marcel Grossmann Meeting held online from July…
Criticality in the collapse of spherically symmetric massless scalar fields in semi-classical loop quantum gravity
Florencia Benítez, Rodolfo Gambini, Steven L. Liebling +1
In a recent paper we showed that the collapse to a black hole in one-parameter families of initial data for massless, minimally coupled scalar fields in spherically symmetric semi-…
Absorption spectroscopy of quantum black holes with gravitational waves
Ivan Agullo, Vitor Cardoso, Adrián del Rio +2
The observation of electromagnetic radiation emitted or absorbed by matter was instrumental in revealing the quantum properties of atoms and molecules in the early XX century, and…
A covariant polymerized scalar field in loop quantum gravity
Florencia Benítez, Rodolfo Gambini, Jorge Pullin
We propose a new polymerization scheme for scalar fields coupled to gravity. It has the advantage of being a (non-bijective) canonical transformation of the fields and therefore en…
