Variational cluster approach to spontaneous symmetry breaking: The itinerant antiferromagnet in two dimensions
C. Dahnken, M. Aichhorn, W. Hanke +2
Based on the self-energy-functional approach proposed recently [M. Potthoff, Eur. Phys. J. B 32, 429 (2003)], we present an extension of the cluster-perturbation theory to systems…
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…
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…
