The renormalization group plays an essential role in many areas of physics, both
conceptually and as a practical tool to determine the long-distance low-energy properties of …

Asymptotic safety is a theoretical proposal for the ultraviolet completion of quantum field
theories, in particular for quantum gravity. Significant progress on this program has led to a …

Asymptotic safety generalizes asymptotic freedom and could contribute to understanding
physics beyond the Standard Model. It is a candidate scenario to provide an ultraviolet …

We present the first direct and nonperturbative computation of the graviton spectral function
in quantum gravity. This is achieved with the help of a novel Lorentzian renormalization …

In this contribution, we discuss the asymptotic safety scenario for quantum gravity with a
functional renormalization group approach that disentangles dynamical metric fluctuations …

The present practice of Asymptotic Safety in gravity is in conflict with explicit calculations in
low energy quantum gravity. This raises the question of whether the present practice meets …

Yang–Mills theories are an important building block of the standard model and in particular
of quantum chromodynamics. Its correlation functions describe the behavior of its …

The asymptotic-safety paradigm posits that the symmetry of quantum theories of gravity and
matter is enhanced to quantum scale symmetry, ie, scale symmetry in the presence of …

We study fixed points of quantum gravity with renormalization group methods and a
procedure to remove convergence-limiting poles from the flow. The setup is tested within the …

We reconstruct the Lorentzian graviton propagator in asymptotically safe quantum gravity
from Euclidean data. The reconstruction is applied to both the dynamical fluctuation graviton …
