Abstract

Thermodynamic and transport properties of a particle subject to a fluctuating gauge field are obtained in two-dimensional space, in the regime where the range of flux correlation is long compared to the thermal length. The resistivity is linear in temperature when the temperature is low compared to the characteristic amplitude of the flux fluctuation. The conductivity shows a non-Drude behavior at finite frequencies. The model has an anomalous response with respect to externally applied magnetic fields: the diamagnetic susceptibility and Hall coefficient vanish at low temperature.
