“…We note that the deconfinement crossover for this value of µ happens for 0.8 Ta 2.0, and that this coincides roughly with the region where the magnetic propagator is enhanced. In contrast to early studies in pure Yang-Mills theory, but in line with a recent study in QCD with twisted-mass Wilson fermions [6], there is no enhancement in the electric mode in the transition region.…”

We investigate 2-colour QCD with 2 flavours of Wilson fermion at nonzero temperature T and quark chemical potential µ, with a pion mass of 700 MeV (m π /m ρ = 0.8). From temperature scans at fixed µ we find that the critical temperature for the superfluid to normal transition depends only very weakly on µ above the onset chemical potential, while the deconfinement crossover temperature is clearly decreasing with µ. We also present results for the Landau-gauge gluon propagator in the hot and dense medium.

“…In Landau gauge they have been computed on the lattice, [13,[30][31][32][33][34][35][36], and in the continuum, [4][5][6] with FRG-methods, extending previous studies in extreme temperature limits in the Dyson-Schwinger framework [30,[37][38][39].…”

We compute the Polyakov loop potential in Yang-Mills theory from the fully dressed primitively divergent correlation functions only. This is done in a variety of functional approaches ranging from functional renormalisation group equations over Dyson-Schwinger equations to two-particle irreducible functionals. We present a confinement criterion that links the infrared behaviour of propagators and vertices to the Polyakov loop expectation value. The present work extends the works of [1-3] to general functional methods and sharpens the confinement criterion presented there. The computations are based on the thermal correlation functions in the Landau gauge calculated in [4][5][6].

“…This latter project built upon the vast set of gauge field configurations from the tmfT collaboration. Our results were published in 2011 and 2012 [56,57] and immediately served as input and benchmark for DSE/FRGE-based studies of the QCD phase diagram (e.g., [55,59]). …”

Abstract. We review lattice calculations of the elementary Greens functions of QCD with a special emphasis on the Landau gauge. These lattice results have been of interest to continuum approaches to QCD over the past 20 years. They are used as reference for Dyson-Schwinger-and functional renormalization group equation calculations as well as for hadronic bound state equations. The lattice provides low-energy data for propagators and three-point vertices in Landau gauge at zero and finite temperature even including dynamical fermions. We summarize Michael Müller-Preußker's important contributions to this field and put them into the perspective of his other research interests.
