The phase structure has been studied from the perspective of the Higgs mechanism, and the relation between a confinement phase and a Higgs phase, in particular the phase continuity. After the short review of the phase structure, we discuss the two-dimensional case, where the gluon propagator in Landau gauge is well described by the Gribov-Zwanziger action. Finally, we may discuss the properties of Dirac eigen-modes in Higgs models. See more QHP seminars
