Asymmetric electron-phonon interactions in the three-band Peierls-Hubbard model
Z. B. Huang, W. Hanke, E. Arrigoni
Using the Quantum Monte Carlo (QMC) technique within frozen-phonon, we studied the effects of the half-breathing O phonon mode on the ground-state properties of the three-ba…

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 of Superconducting and Antiferromagnetic Gaps in High-Tc Compounds: a Test Case for a Microscopic Theory
Werner Hanke, Marc G. Zacher, Enrico Arrigoni +1
Recent angle resolved photoemission (ARPES) data, which found evidence for a d-wave-like modulation of the antiferromagnetic gap, suggest an intimate interrelation between the anti…
