The nonperturbative functional renormalization group and its applications

N Dupuis, L Canet, A Eichhorn, W Metzner… - Physics Reports, 2021 - Elsevier
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 …

QCD running couplings and effective charges

A Deur, SJ Brodsky, CD Roberts - Progress in Particle and Nuclear Physics, 2024 - Elsevier
We discuss our present knowledge of α s, the fundamental running coupling or effective
charge of Quantum Chromodynamics (QCD). A precise understanding of the running of α s …

QCD phase structure at finite temperature and density

W Fu, JM Pawlowski, F Rennecke - Physical Review D, 2020 - APS
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 …

Aspects of the functional renormalisation group

JM Pawlowski - Annals of Physics, 2007 - Elsevier
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 …

Functional renormalization group approach to correlated fermion systems

W Metzner, M Salmhofer, C Honerkamp, V Meden… - Reviews of Modern …, 2012 - APS
Numerous correlated electron systems exhibit a strongly scale-dependent behavior. Upon
lowering the energy scale, collective phenomena, bound states, and new effective degrees …

P Kopietz, L Bartosch, F Schütz - 2010 - books.google.com
This book, based on a graduate course given by the authors, is a pedagogic and self-
contained introduction to the renormalization group with special emphasis on the functional …

QCD at finite temperature and density within the fRG approach: an overview

W Fu - Communications in Theoretical Physics, 2022 - iopscience.iop.org
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 …

QCD phase structure from functional methods

F Gao, JM Pawlowski - Physical Review D, 2020 - APS
We discuss the QCD phase structure at finite temperature and chemical potential for 2-flavor
and 2+ 1-flavor QCD. The results are achieved by computing QCD correlation functions …

Chiral symmetry breaking in continuum QCD

M Mitter, JM Pawlowski, N Strodthoff - Physical Review D, 2015 - APS
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 …
