“…The DSEs are the equations of motion for these correlation functions. The non-perturbative DSEs' studies of two point correlation functions are extensively used in various topics, such as hadron physics [4], thermal and dense QCD systems [16][17][18], chiral phase transition in 2+1 dimensional quantum electrodynamics (QED 3 ) [19,20]. Herein, we briefly introduce gap equations and elaborate the algorithm of quasi-Wigner solution with finite current quark mass.…”

We propose a new algorithm to solve the quasi-Wigner solution of the gap equation beyond chiral limit. Employing a Gaussian gluon model and rainbow truncation, we find that the quasi-Wigner solution exists in a limited region of current quark mass, m < 43.1 MeV, at zero temperature T and zero chemical potential µ. The difference between Cornwall-Jackiw-Tomboulis (CJT) effective actions of quasi-Wigner and Nambu-Goldstone solutions shows that the Nambu-Goldstone solution is chosen by physics. Moreover, the quasi-Wigner solution is studied at finite temperature and chemical potential, the far infrared mass function of quasi-Wigner solution is negative and decrease along with T at µ = 0. Its susceptibility is divergent at certain temperature with small m, and this temperature decreases along with m. Taking T = 80 MeV as an example, the quasi-Wigner solution is shown at finite chemical potential upto µ = 350 MeV as well as Nambu solution, the coexistence of these two solutions indicates that the QCD system suffers the first order phase transition. The first order chiral phase transition line is determined by the difference of CJT effective actions.

In this paper, we investigate dynamical mass generation in (2+1)-dimensional quantum electrodynamics at finite temperature. Many studies are carried out within the instantaneous-exchange approximation, which ignores all but the zero-frequency component of the boson propagator and fermion self-energy function. We extend these studies by taking the retardation effects into consideration. In this paper, we get the explicit frequency n and momentum p dependence of the fermion self-energy function and identify the critical temperature for different fermion flavors in the chiral limit. Also, the phase diagram for spontaneous symmetry breaking in the theory is presented in Tc-N f space. The results show that the chiral condensate is just one-tenth of the scale of previous results, and the chiral symmetry is restored at a smaller critical temperature.
