Query: Quantum critical points with the Coulomb interaction and the dynamical
  exponent: when and why z=1   A general scenario that leads to Coulomb quantum criticality with the
dynamical critical exponent z=1 is proposed. I point out that the long-range
Coulomb interaction and quenched disorder have competing effects on z, and that
the balance between the two may lead to charged quantum critical points at
which z=1 exactly. This is illustrated with the calculation for the Josephson
junction array Hamiltonian in dimensions D=3-\epsilon. Precisely in D=3,
however, the above simple result breaks down, and z>1. Relation to other
theoretical studies is discussed.
