Emergent Hadrons and Diquarks
Kenji Fukushima, Jan M. Pawlowski, Nils Strodthoff
We discuss the emergence of a low-energy effective theory with quarks, mesons, diquarks and baryons at vanishing and finite baryon density from first principle QCD. The present wor…
Correlation functions of three-dimensional Yang-Mills theory from the FRG
Lukas Corell, Anton K. Cyrol, Mario Mitter +2
We compute correlation functions of three-dimensional Landau-gauge Yang-Mills theory with the Functional Renormalisation Group. Starting from the classical action as only input, we…
Non-perturbative finite-temperature Yang-Mills theory
Anton K. Cyrol, Mario Mitter, Jan M. Pawlowski +1
We present non-perturbative correlation functions in Landau-gauge Yang-Mills theory at finite temperature. The results are obtained from the functional renormalisation group within…
Non-perturbative quark, gluon and meson correlators of unquenched QCD
Anton K. Cyrol, Mario Mitter, Jan M. Pawlowski +1
We present non-perturbative first-principle results for quark-, gluon- and meson PI correlation functions of two-flavour Landau-gauge QCD in the vacuum. These correlation functi…
FormTracer - A Mathematica Tracing Package Using FORM
Anton K. Cyrol, Mario Mitter, Nils Strodthoff
We present FormTracer, a high-performance, general purpose, easy-to-use Mathematica tracing package which uses FORM. It supports arbitrary space and spinor dimensions as well as an…
Landau gauge Yang-Mills correlation functions
Anton K. Cyrol, Leonard Fister, Mario Mitter +2
We investigate Landau gauge Yang-Mills theory in a systematic vertex expansion scheme for the effective action with the functional renormalisation group. Particular focus i…
Real time correlation functions and the functional renormalisation group
Jan M. Pawlowski, Nils Strodthoff
We put forward a functional renormalisation group approach for the direct computation of real time correlation functions, also applicable at finite temperature and density. We cons…
Chiral symmetry breaking in continuum QCD
Mario Mitter, Jan M. Pawlowski, Nils Strodthoff
We present a quantitative analysis of chiral symmetry breaking in two-flavour continuum QCD in the quenched limit. The theory is set-up at perturbative momenta, where asymptotic fr…
Transport Coefficients in Yang--Mills Theory and QCD
Nicolai Christiansen, Michael Haas, Jan M. Pawlowski +1
We calculate the shear viscosity over entropy density ratio in Yang--Mills theory from the Kubo formula using an exact diagrammatic representation in terms of full propagator…
Towards quantitative precision in the chiral crossover: masses and fluctuation scales
Alexander J. Helmboldt, Jan M. Pawlowski, Nils Strodthoff
We investigate the relation between the physical pion pole and screening masses and the mesonic fluctuation scale in low-energy QCD, which relates to the curvature of the mesonic e…
Spectral Functions for the Quark-Meson Model Phase Diagram from the Functional Renormalization Group
Ralf-Arno Tripolt, Nils Strodthoff, Lorenz von Smekal +1
We present a method to obtain spectral functions at finite temperature and density from the Functional Renormalization Group. Our method is based on a thermodynamically consistent…
Polyakov-Quark-Meson-Diquark Model for two-color QCD
Nils Strodthoff, Lorenz von Smekal
We present an update on the phase diagram of two-color QCD from a chiral effective model approach based on a quark-meson-diquark model using the Functional Renormalization Group (F…
Real-Time Correlation Functions in the O(N) Model from the Functional Renormalization Group
Kazuhiko Kamikado, Nils Strodthoff, Lorenz von Smekal +1
In the framework of the functional renormalization group (FRG) we present a simple truncation scheme for the computation of real-time mesonic n-point functions, consistent with the…
Fluctuations in the quark-meson model for QCD with isospin chemical potential
Kazuhiko Kamikado, Nils Strodthoff, Lorenz von Smekal +1
We study the two-flavor quark-meson (QM) model with the functional renormalization group (FRG) to describe the effects of collective mesonic fluctuations on the phase diagram of QC…
Quark-meson-diquark model for two-color QCD
Nils Strodthoff, Bernd-Jochen Schaefer, Lorenz von Smekal
We introduce a two-flavor quark-meson-diquark model for two-color QCD and its extensions to include gauge-field dynamics as described by the Polakov loop. Grand potential and phase…
Universal Aspects of Deconfinement in 2+1 Dimensions
Lorenz von Smekal, Sam R Edwards, Nils Strodthoff
The 2+1 dimensional pure SU(N) gauge theories with N <= 4 are candidates for applying the powerful tools of scaling and universality to their deconfinement transitions at finite te…
