Correlated band structure of electron-doped cuprate materials

C. Dahnken, M. Potthoff, E. Arrigoni +1

We present a numerical study of the doping dependence of the spectral function of the n-type cuprates. Using a variational cluster-perturbation theory approach based upon the self-…

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…

Variational cluster approach to correlated electron systems in low dimensions

M. Potthoff, M. Aichhorn, C. Dahnken

A self-energy-functional approach is applied to construct cluster approximations for correlated lattice models. It turns out that the cluster-perturbation theory (Senechal et al, P…

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…

Theory of ARPES intensities from the CuO plane

C. Dahnken, R. Eder

We present a theory for the photon energy and polarization dependence of ARPES intensities from the CuO plane in the framework of strong correlation models. We show that for el…
