Approximate Killing symmetries in non-perturbative quantum gravity
Joren Brunekreef, Marcus Reitz
It is an open question whether fluctuations at the Planck scale in a non-perturbative theory of quantum gravity behave in such a way that the resulting semi-classical geometry can…

Geometric flux formula for the gravitational Wilson loop
N. Klitgaard, R. Loll, Marcus Reitz +1
Finding diffeomorphism-invariant observables to characterize the properties of gravity and spacetime at the Planck scale is essential for making progress in quantum gravity. The ho…
