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…
Exact Renormalisation Group Equations and Loop Equations for Tensor Models
Thomas Krajewski, Reiko Toriumi
In this paper, we review some general formulations of exact renormalisation group equations and loop equations for tensor models and tensorial group field theories. We illustrate t…
Polchinski's exact renormalisation group for tensorial theories: Gaussian universality and power counting
Thomas Krajewski, Reiko Toriumi
In this paper, we use the exact renormalisation in the context of tensor models and tensorial group field theories. As a byproduct, we rederive Gaussian universality for random ten…
Scale-Dependent Newton's Constant G in the Conformal Newtonian Gauge
Herbert W. Hamber, Reiko Toriumi
In classical gravity deviations from the predictions of the Einstein theory are often discussed within the framework of the conformal Newtonian gauge, where scalar perturbations ar…
Cosmological Density Perturbations with a Scale-Dependent Newton's G
Herbert W. Hamber, Reiko Toriumi
We explore possible cosmological consequences of a running Newton's constant , as suggested by the non-trivial ultraviolet fixed point scenario in the quantum field-t…
