dc.descriptionWe calculate Fermi-surface properties of the Cuprate superconductors within the three-band Hubbard model using a cluster expansion for the proper self-energy. The Fermi-surface topology is in agreement with angular-resolved photoemission data for dopings $\sim 20\%$. We discuss possible violations of the Luttinger sum-rule for smaller dopings and the role of van-Hove singularities in the density of states of the Zhang-Rice singlets. We calculate the shift in the chemical potential upon doping and find quantitative agreement with recent experiments.
