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…
Towards theory constraints on ultralight dark matter from quantum gravity
Gabriel Assant, Astrid Eichhorn, Benjamin Knorr
Ultralight scalar dark matter may couple to the Standard Model through dimension-five operators that contain the field-strength tensors of the gauge interactions. Recent progress i…
Comment on Path integral measure and RG equations for gravity
Aaron Held, Benjamin Knorr, Jan M. Pawlowski +4
Asymptotic safety is a candidate for a predictive quantum theory of gravity and matter. Recent works (arXiv:2412.10194 and arXiv:2412.14108) challenged this scenario. We show that…
Asymptotic safety, quantum gravity, and the swampland: a conceptual assessment
Ivano Basile, Benjamin Knorr, Alessia Platania +1
We provide a conceptual assessment of some aspects of fundamental quantum field theories of gravity in light of foundational aspects of the swampland program. On the one hand, asym…
Visions in Quantum Gravity
Luca Buoninfante, Benjamin Knorr, K. Sravan Kumar +36
To deepen our understanding of Quantum Gravity and its connections with black holes and cosmology, building a common language and exchanging ideas across different approaches is cr…
Lectures in Quantum Gravity
Ivano Basile, Luca Buoninfante, Francesco Di Filippo +3
Formulating a quantum theory of gravity lies at the heart of fundamental theoretical physics. This collection of lecture notes encompasses a selection of topics that were covered i…
Unearthing the intersections: positivity bounds, weak gravity conjecture, and asymptotic safety landscapes from photon-graviton flows
Benjamin Knorr, Alessia Platania
We compute the asymptotic safety landscape stemming from ultraviolet-complete photon-graviton flows in a field theoretic setup, and we confront it with the weak gravity conjecture…
One-loop renormalisation of cubic gravity in six dimensions
Benjamin Knorr
We present the complete set of universal one-loop beta functions of cubic gravity in six dimensions. The system admits over 8000 distinct fixed points, of which more than 200 are r…
