Non-Perturbative -matrix Renormalization
Laurent Freidel, José Padua-Argüelles, Susanne Schander +1
We propose a renormalization group flow equation for a functional that generates -matrix elements and which captures similarities to the well-known Wetterich and Polchinski equa…
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…
Yukawa interactions in Quantum Gravity
Gustavo P. de Brito, Manuel Reichert, Marc Schiffer
We present the first complete next-to-leading-order analysis of a Yukawa system within the framework of asymptotically safe quantum gravity. Our results are obtained through a syst…
Asymptotically safe quantum gravity: functional and lattice perspectives
Marc Schiffer
Asymptotically safe quantum gravity is a candidate theory to quantum gravity, which could unify the gravitational interaction with particle physics. It is characterized by quantum…
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…
