Mechanism of High Temperature Superconductivity in a striped Hubbard Model
E. Arrigoni, E. Fradkin, S. A. Kivelson
It is shown, using asymptotically exact methods, that the two dimensional repulsive Hubbard model with strongly modulated interactions exhibits ``high temperature superconductivity…

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…
