Interrelation between antiferromagnetic and superconducting gaps in high-Tc materials
E. Arrigoni, M. G. Zacher, T. Eckl +1
We propose a phenomenological model, comprising a microscopic \sof model plus the on-site Hubbard interaction (``projected \sof model'') to understand the interrelation between…
Evolution of the stripe phase as a function of doping from a theoretical analysis of angle-resolved photoemission data
Marc G. Zacher, Robert Eder, Enrico Arrigoni +1
By comparing single-particle spectral functions of t-J and Hubbard models with recent angle-resolved photoemission (ARPES) results for LSCO and Nd-LSCO, we can decide where holes g…
Stripes in Doped Antiferromagnets: Single-Particle Spectral Weight
Marc G. Zacher, Robert Eder, Enrico Arrigoni +1
Recent photoemission (ARPES) experiments on cuprate superconductors provide important guidelines for a theory of electronic excitations in the stripe phase. Using a cluster perturb…
Interrelation of Superconducting and Antiferromagnetic Gaps in High-Tc Compounds: a Test Case for the SO(5) Theory
Marc G. Zacher, Werner Hanke, Enrico Arrigoni +1
Recent angle resolved photoemission data, which found evidence for a d-wave-like modulation of the antiferromagnetic gap, suggest an intimate interrelation between the antiferromag…
Strong coupling theory for the Hubbard model
A. Dorneich, M. G. Zacher, C. Groeber +1
We reanalyze the Hubbard-I approximation by showing that it is equivalent to an effective Hamiltonian describing Fermionic charge fluctuations, which can be solved by Bogoliubov tr…

Werner Hanke, Marc G. Zacher, Enrico Arrigoni +1
