Diffeomorphism-invariant Approach to Asymptotically Safe Quantum Gravity
Friederike Ihssen, Benjamin Knorr, Silas Mezger +2
We provide a novel diffeomorphism-invariant approach to asymptotically safe metric quantum gravity. It is based on physics-informed renormalisation group flows with a renormalisati…

Asymptotically (un)safe scattering amplitudes from scratch: a deep dive into the IR jungle
Benjamin Knorr
We compute leading order quantum gravity contributions to a simple scalar scattering amplitude in Asymptotic Safety. Our model admits an analytic treatment so that several subtleti…
