Application of a lindhard like model for normal state transport properties of the cuprate superconductors

We account for the transport properties of the cuprates and of organic superconductors in the normal state by a model in which, following Lindhard's theory, the velocity near the Fermi surface is increased by reduced screening. We show that the conductivity due to elastic scattering becomes temperature dependent. We account for the conductivity anisotropy, the thermoelectric power, and the Hall constant. An analysis of the London penetration depth, which takes into account the low dimensionality of the conduction, gives large Fermi velocities and small effective masses, consistent with the analysis of the transport properties.
