Spectral Properties of High-T Cuprates via a Cluster-Perturbation Approach
C. Dahnken, E. Arrigoni, W. Hanke
Angular-resolved photoemission data on half-filled doped cuprate materials are compared with an exact-diagonalization analysis of the three-band Hubbard model, which is extended to…

Interrelation between antiferromagnetic and superconducting gaps in high-Tc materials
E. Arrigoni, M. G. Zacher, T. Eckl +1
We propose a phenomenological model, comprising a microscopic \sof model plus the on-site Hubbard interaction (``projected \sof model'') to understand the interrelation between…
