Abstract
We derive the fermionic contribution to the longitudinal and Hall conductivities within a Kubo formalism, using a phenomenological Green’s function which has been previously developed to describe photoemission data in the pseudogap phase of the cuprates. We find that the in-plane electrical and thermal conductivities are metalliclike, showing a universal limit behavior characteristic of a -wave spectrum as the scattering rate goes to zero. In contrast, the -axis resistivity and the Hall number are insulatinglike, being divergent in the same limit. The relation of these results to transport data in the pseudogap phase is discussed.
