Abstract
We analyze here the behavior of the Hall conductivity (formula presented) near a (formula presented) 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 (formula presented), and depends nonmonotonically on H once (formula presented) is weak enough. (formula presented) passes through a maximum at (formula presented) in the quantum critical regime, suggesting that the limits (formula presented) and (formula presented) do not commute.
