Description

We study analytically the effect of magnetic interactions on dynamical symmetry breaking in strongly coupled quantum electrodynamics. By solving the Schwinger-Dyson equation for the electron propagator in the asymptotic region with the inclusion of magnetic effects in the vertex function, we find a nonperturbative solution whose existence indicates a spontaneous breaking of chiral symmetry with a critical coupling constant depending on the magnetic-interaction strength
