On quantum gravity and quantum gravity phenomenology [PDF]

open access: yesThe Sixteenth Marcel Grossmann Meeting, 2021
This article summarizes a new approach to quantum gravity based on the concepts of modular spacetime, Born geometry, and metastring theory and their applications to quantum gravity phenomenology.

Quantum Gravity Phenomenology [PDF]

open access: yesarXiv, 2003
I give a brief non-technical review of "Quantum Gravity Phenomenology" and in particular I describe some studies which should soon allow to establish valuable data-based constraints on the short-distance structure of spacetime.

A short review of loop quantum gravity [PDF]

open access: yesReports on progress in physics. Physical Society, 2021
An outstanding open issue in our quest for physics beyond Einstein is the unification of general relativity (GR) and quantum physics. Loop quantum gravity (LQG) is a leading approach toward this goal.

Quantum Gravity in 30 Questions [PDF]

open access: yesProceedings of Corfu Summer Institute 2021 "School and Workshops on Elementary Particle Physics and Gravity" — PoS(CORFU2021), 2022
Quantum gravity is the missing piece in our understanding of the fundamental interactions today. Given recent observational breakthroughs in gravity, providing a quantum theory for what lies beyond general relativity is more urgent than ever.

Solvable models of quantum black holes: a review on Jackiw–Teitelboim gravity [PDF]

open access: yesLiving Reviews in Relativity, 2022
We review recent developments in Jackiw–Teitelboim gravity. This is a simple solvable model of quantum gravity in two dimensions (that arises e.g. from the s-wave sector of higher dimensional gravity systems with spherical symmetry).

Quantum Gravity in the Lab. II. Teleportation by Size and Traversable Wormholes [PDF]

open access: yesPRX Quantum, 2021
In [1] we discussed how quantum gravity may be simulated using quantum devices and gave a specific proposal -- teleportation by size and the phenomenon of size-winding.

Spherically symmetric loop quantum gravity: analysis of improved dynamics [PDF]

open access: yesClassical and quantum gravity, 2020
We study the ‘improved dynamics’ for the treatment of spherically symmetric space-times in loop quantum gravity introduced by Chiou et al in analogy with the one that has been constructed by Ashtekar, Pawlowski and Singh for the homogeneous space-times ...

Let Loop Quantum Gravity and Affine Quantum Gravity Examine Each Other [PDF]

open access: yesJournal of High Energy Physics, Gravitation and Cosmology > Vol.7 No.3, July 2021, 2021
Loop Quantum Gravity is widely developed using canonical quantization in an effort to find the correct quantization for gravity. Affine quantization, which is like canonical quantization augmented bounded in one orientation, e.g., a strictly positive coordinate. We open discussion using canonical and affine quantizations for two simple problems so each

Black hole collapse and bounce in effective loop quantum gravity [PDF]

open access: yesClassical and quantum gravity, 2020
We derive effective equations with loop quantum gravity corrections for the Lemaître–Tolman–Bondi family of space-times, and use these to study quantum gravity effects in the Oppenheimer–Snyder collapse model.
