This paper analyzes the critical behavior associated with spontaneous breakdown of chiral symmetry in QED{sub 3} (three-dimensional QED) with four-component Dirac fermion using the SD (Schwinger-Dyson) equation. In the quenched planar approximation, the authors find an approximate solution such that QED{sub 3} resides in only one phase where the chiral symmetry is broken. Moreover, the authors predict the scaling law for the dynamical mass and chiral order parameter by an analytic study of the SD equation, which is then confirmed by solving the SD equation numerically. This scaling law is consistent with the Monte Carlo result in the quenched approximation.
