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 …

We review results for the phase diagram of QCD, the properties of quarks and gluons and
the resulting properties of strongly interacting matter at finite temperature and chemical …

We discuss the phase structure of QCD for N f= 2 and N f= 2+ 1 dynamical quark flavors at
finite temperature and baryon chemical potential. It emerges dynamically from the …

For decades, frustrated quantum magnets have been a seed for scientific progress and
innovation in condensed matter. As much as the numerical tools for low-dimensional …

We investigate Landau gauge SU (3) Yang-Mills theory in a systematic vertex expansion
scheme for the effective action with the functional renormalization group. Particular focus is …

In this paper, we present an overview on recent progress in studies of QCD at finite
temperature and densities within the functional renormalization group (fRG) approach. The …

The chiral condensate, which is constant in vacuum, may become spatially modulated at
moderately high densities where in the traditional picture of the QCD phase diagram a first …

We present a quantitative analysis of chiral symmetry breaking in two-flavor continuum QCD
in the quenched limit. The theory is set up at perturbative momenta, where asymptotic …

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 …

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 …
