Abstract

Since the massless quantum electrodynamics in 2+1 dimensions (QED3) with nonzero gauge boson mass ζ can be used to explain some important traits of high-Tc superconductivity in planar cuprates, it is worthwhile to apply this model to analyze the nature of chiral phase transition at the critical value ζc. Based on the feature of chiral susceptibility, we show that the system at ζc exhibits a second-order phase transition which accords with the nature of appearance of the high-Tc superconductivity, and the estimated critical exponents around ζc are illustrated.
