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…

Phase diagram and dynamics of the projected SO(5)-symmetric model of high- superconductivity
A. Dorneich, W. Hanke, E. Arrigoni +2
We present numerical studies of a quantum ``projected'' SO(5) model which aims at a unifying description of antiferromagnetism and superconductivity in the high-T cuprates, whi…
