Abstract

We analyze here the behavior of the Hall conductivity σxy near a z = 2 insulator-superconductor quantum critical point in a perpendicular magnetic field. We show that the form of the conductivity is sensitive to the presence of dissipation η, and depends nonmonotonically on H once η is weak enough. σxy passes through a maximum at H ∼ ηT in the quantum critical regime, suggesting that the limits H→0 and η→0 do not commute.
