Canonical quantization of non-commutative holonomies in 2+1 loop quantum gravity [PDF]

open access: yesJournal of High Energy Physics, 2011
In this work we investigate the canonical quantization of 2+1 gravity with cosmological constant $\Lambda>0$ in the canonical framework of loop quantum gravity.

Canonical quantum gravity and consistent discretizations [PDF]

open access: yesPramana, 2004
This is a summary of the talk presented by JP at ICGC2004. It covered some developments in canonical quantum gravity occurred since ICGC2000, emphasizing the recently introduced consistent discretizations of general relativity.

Nonperturbative solutions for canonical quantum gravity: An overview [PDF]

open access: yesPhysics Reports, 1997
In this paper we will make a survey of solutions to the Wheeler-Dewitt equation which have been found up to now in Ashtekar's formulation for canonical quantum gravity. Roughly speaking they are classified into two categories, namely, Wilson-loop solutions and topological solutions.

PARAMETRIZING FLUIDS IN CANONICAL QUANTUM GRAVITY [PDF]

open access: yesInternational Journal of Modern Physics A, 2008
The problem of time is an unsolved issue of canonical General Relativity. A possible solution is the Brown-Kuchaƙ mechanism which couples matter to the gravitational field and recovers a physical, i.e. non vanishing, observable Hamiltonian functional by manipulating the set of constraints. Two cases are analyzed.

Potential tests of the generalized uncertainty principle in the advanced LIGO experiment

open access: yesPhysics Letters B, 2018
The generalized uncertainty principle and a minimum measurable length arise in various theories of gravity and predict Planck-scale modifications of the canonical position-momentum commutation relation.

Fundamental length scale and the bending of light in a gravitational field

open access: yesEuropean Physical Journal C: Particles and Fields, 2022
The canonical approach to quantizing quantum gravity is understood to suffer from pathological non-renomalizability. Nevertheless in the context of effective field theory, a viable perturbative approach to calculating elementary processes is possible ...

Hamiltonian Renormalization V: Free Vector Bosons

open access: yesFrontiers in Astronomy and Space Sciences, 2021
In a recent proposal we applied methods from constructive QFT to derive a Hamiltonian Renormalization Group in order to employ it ultimately for canonical quantum gravity.

Three-dimensional canonical quantum gravity [PDF]

open access: yesClassical and Quantum Gravity, 1995
General aspects of vielbein representation, ADM formulation and canonical quantization of gravity are reviewed using pure gravity in three dimensions as a toy model. The classical part focusses on the role of observers in general relativity, which will later be identified with quantum observers.
