Description
We present exact results for small clusters of CuO2 units including intra-atomic and interatomic Coulomb interactions. We calculate one-particle spectral densities for doped and undoped systems and show that the results are in qualitative agreement with spectroscopic experiments. We also present results for spin and charge dynamics as well as the current-current correlation functions
