The role of Background Independence for Asymptotic Safety in Quantum Einstein Gravity

Martin Reuter, Holger Weyer

We discuss various basic conceptual issues related to coarse graining flows in quantum gravity. In particular the requirement of background independence is shown to lead to renorma…

Conformal sector of Quantum Einstein Gravity in the local potential approximation: non-Gaussian fixed point and a phase of unbroken diffeomorphism invariance

Martin Reuter, Holger Weyer

We explore the nonperturbative renormalization group flow of Quantum Einstein Gravity (QEG) on an infinite dimensional theory space. We consider "conformally reduced" gravity where…

Background Independence and Asymptotic Safety in Conformally Reduced Gravity

Martin Reuter, Holger Weyer

We analyze the conceptual role of background independence in the application of the effective average action to quantum gravity. Insisting on a background independent renormalizati…

On the Possibility of Quantum Gravity Effects at Astrophysical Scales

M. Reuter, H. Weyer

The nonperturbative renormalization group flow of Quantum Einstein Gravity (QEG) is reviewed. It is argued that at large distances there could be strong renormalization effects, in…

Do we Observe Quantum Gravity Effects at Galactic Scales?

M. Reuter, H. Weyer

The nonperturbative renormalization group flow of Quantum Einstein Gravity (QEG) is reviewed. It is argued that there could be strong renormalization effects at large distances, in…

Quantum Gravity at Astrophysical Distances?

M. Reuter, H. Weyer

Assuming that Quantum Einstein Gravity (QEG) is the correct theory of gravity on all length scales we use analytical results from nonperturbative renormalization group (RG) equatio…
