QED3 at finite temperature and density

Year: 2014

Type: article

Abstract: Schwinger-Dyson equations are used to study the chiral phase diagram of QED in three dimensions. This computation is made with full frequency dependence in the two-point function gap equations for the first time. We also demonstrate that reliable results are attainable in spite of an infrared divergence that is endemic to the theory. A theoretically sound method for dealing with cutoff ultraviolet regulators is presented. Finally, it is shown that the quenched and instantaneous approximations often used in the literature are inaccurate.
