Abstract

We correct our previous conclusion regarding the fate of a charged quantum critical point across the superconducting transition for two dimensional massless Dirac fermion. Within the leading order ϵ\epsilon expansion, we now find that the requisite number of four-component Dirac fermion flavors (NfN_f) for the continuous phase transition through a charged critical point is Nf>18.2699N_f>18.2699. For Nf1/2N_f\geq1/2, the critical number of bosonic flavors for this transition is significantly reduced as compared to the value determined in the absence of the Dirac fermions in the theory.
