Finite Temperature Landau Gauge Lattice Quark Propagator

Understand

The quark propagator at finite temperature is investigated using quenched gauge configurations.

• The propagator form factors are investigated for temperatures above and below the gluon deconfinement temperature $T_c$ and for the various Matsubara frequencies.
• Significant differences between the functional behaviour below and above $T_c$ are observed both for the quark wave function and the running quark mass.
• The results for the running quark mass indicate a strong link between gluon dynamics, the mechanism for chiral symmetry breaking and the deconfinement mechanism.
