Query: Note on "Quantum superconducting criticality in graphene and topological
  insulators"   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 $\epsilon$ expansion, we now
find that the requisite number of four-component Dirac fermion flavors ($N_f$)
for the continuous phase transition through a charged critical point is
$N_f>18.2699$. For $N_f\geq1/2$, 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.
