Chiral and deconfinement transition from Dyson-Schwinger equations

Understand

We determine the quark condensate and the dressed Polyakov loop from the finite temperature Landau gauge quark propagator evaluated with U(1)-valued boundary conditions in an approximation to quenched QCD.

• These gauge invariant quantities allow for an investigation of the chiral and deconfinement transition.
• We compare results from Dyson-Schwinger equations on a lattice with infinite volume continuum results and study the temperature and quark mass dependence of both quantities.
• In particular we investigate the chiral condensate and the dressed Polyakov loop in the chiral limit.
