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 …

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

We discuss structural aspects of the functional renormalisation group. Flows for a general
class of correlation functions are derived, and it is shown how symmetry relations of the …

We review and extend in several directions recent results on the “asymptotic safety”
approach to quantum gravity. The central issue in this approach is the search of a Fixed …

The theory of the strong interaction, quantum chromodynamics (QCD), describes the
generation of hadronic masses and the state of hadronic matter during the early stages of …

This article reviews recent advances in the theory of the three-dimensional dilute
homogeneous Bose gas at zero and finite temperature. Effective-field-theory methods are …

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 …

The Polyakov-extended quark–meson model (PQM) is investigated beyond mean-field. This
represents an important step towards a fully dynamical QCD computation. Both the quantum …

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 …
