Investigation of the confinement in massive QED3

Abstract

By the application of the Schwinger function, the deconfinement in massive quantum electrodynamics in [Formula: see text]-dimensional (QED3) is investigated. It is shown that oscillating behavior of the Schwinger function gradually disappears with fermion mass increasing based on coupled Dyson–Schwinger equations in massive QED3. On the other hand, we have shown that the confined fermion transfers gradually into the phase of deconfinement with the increasing boson mass, which is consistent with the result in the case of massless QED3. Finally, we emphasized that dynamical chiral symmetry breaking and confinement always appear simultaneously in massive QED3.
