The spin-charge coupling parameter is associated to the doping fraction in the cuprates. The model is able to account for the various phases of the cuprates and their properties, not only at low and intermediate doping but also for (highly) over-doped compounds. We acquire a qualitative understanding of highTc superconductivity as a Bose-Einstein condensation of boun d charge pairs. eng open access A lattice field theoretical model for high-T_(c) superconductivity journal article
