The superconducting gap in the Hubbard model and the two gap energy scales in high-Tc cuprates
M. Aichhorn, E. Arrigoni, Z. B. Huang +1
Recent excperiments (ARPES, Raman) suggest the presence of two distinct energy gaps in high-Tc superconductors (HTSC), exhibiting different doping dependences. Results of a variati…
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…
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…
