Abstract Based on the Cornwall–Jackiw–Tomboulis effective potential and the truncated Dyson–Schwinger equations, the nature of phase transition of thermal QED $$_3$$ 3 at finite volume is investigated. We show that, with the rise of temperature

In this paper, we study the dynamical mass generation in the Abelian Higgs model in 2 + 1 dimensions. Instead of adopting the approximations in [Jiang H et al., J. Phys. A 41 2008 255402.], we numerically solve the coupled Dyson–Schwinger Equations

Dynamical chiral symmetry breaking (DCSB) in thermal QED3 with fermion velocity is studied in the framework of Dyson-Schwinger equations. By adopting instantaneous approximation and neglecting the transverse component of gauge boson propagator at fin

The influence of finite-volume effects on dynamical chiral symmetry breaking of thermal ${\mathrm{QED}}_{3}$ is investigated. We show that the chiral symmetry gets restored at all temperatures when the size of system is less than some certain value $

According to the extensive theoretical and experimental investigations, it is widely accepted that the long-range Coulomb interaction is too weak to generate a dynamical excitonic gap in graphene with a perfect Dirac cone. We study the impact of the

In this paper, we investigate the behaviors of dual fermion condensate in QED3 under variation of temperature. By means of Dyson-Schwinger equation for the fermion propagator, we extract the dual fermion condensate and compare its behavior with the o
