Gravitational Lensing Effects from Models of Loop Quantum Gravity with Rigorous Quantum Parameters

Universe
Many previous works have studied gravitational lensing effects from Loop Quantum Gravity. So far, gravitational lensing effects from Loop Quantum Gravity have only been studied by choosing large quantum parameters much larger than the Planck scale ...

Elementary Model for Quantum Gravity

Physical Review D, 1970
An elementary model of the gravitational field in the presence of external sources is studied. This model has positivity requirements, invariance under transformations, and nonlinear equations of motion, all of which are analogs of similar properties in the full theory.

Toy Models of Quantum Gravity

2022
In this dissertation we use simple models of quantum gravity to study the AdS/CFT correspondence. The main focus is on Jackiw-Teitelboim (JT) gravity, an exactly solvable two-dimensional model. We first show how to enrich JT gravity with dynamical End-of-the-World (EoW) branes.

RELATIONAL SPACETIME, MODEL CATEGORIES AND QUANTUM GRAVITY

International Journal of Modern Physics A, 2009
We propose a mathematically concrete way of modelling the suggestion that in quantum gravity the spacetime manifold disappears. We replace the underlying point set topological space with several apparently different models, which are actually related by pairs of adjoint functors from rational homotopy theory.
