At zeroth order, the model exhibits approximate particle-vortex self-dual electrical transport. Corrections of 1/Nf due to fluctuations in the Chern-Simons gauge field and disorder produce violations of self-duality. We find these violations would be supressed when the Coulomb interaction is present.
