Abstract

In this lecture we present some interesting issues that arise when the dynamics of the charge carriers in the CuO2 planes of high temperature superconductors is considered. Based on the qualitative picture of doping, set by experiments and some previous calculations, we consider the strength of the various inter- and intra-cell charge transfer susceptibilities, the question of Coulomb screening and charge collective-modes. The starting point is the usual p-d model extended by the long-range Coulomb (LRC) interaction. Within this model it is possible to examine the case in which the LRC forces frustrate the electronic phase separation, the instability which is present in the model without a LRC interaction. While the static dielectric function in such systems is negative down to arbitrarily small wavevectors, the system is not unstable. We consider the dominant electronic charge susceptibilities and possible consequences for the lattice properties.
