The exploration of the universe has recently entered a new era thanks to the multi-
messenger paradigm, characterized by a continuous increase in the quantity and quality of …

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

A bstract We study the ultraviolet behaviour of four-dimensional quantum field theories
involving non-abelian gauge fields, fermions and scalars in the Veneziano limit. In a regime …

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

New physics beyond the Standard Model can give rise to stochastic gravitational-wave
backgrounds, for example, through cosmic strings. In this way, gravitational-wave searches …

The asymptotic safety conjecture is examined for quantum gravity in four dimensions. Using
the renormalization group, we find evidence for an interacting UV fixed point for polynomial …

Quantum gravity is the missing piece in our understanding of the fundamental interactions
today. Given recent observational breakthroughs in gravity, providing a quantum theory for …

We study the asymptotic safety conjecture for quantum gravity in the presence of matter
fields. A general line of reasoning is put forward explaining why gravitons dominate the high …

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 …
