Spectral properties of strongly correlated electron systems
We investigate the single particle static and dynamic properties at zero temperature within the Hubbard an three-band-Hubbard model for the superconducting copper oxides. Based on the recently proposed self-energy functional approach (SFA) [M.Potthoff, Eur. Phys. J. B 32 429 (2003)], we present an …

Hochfeld/Hochfrequenz-Elektronenspin-Resonanz an Übergangsmetallverbindungen mit starken elektronischen Korrelationen
Starke elektronische Korrelationen und die daraus resultierenden vielfältigen Phänomenen sind Gegenstand der modernen Festkörperphysik. Solche Korrelationen finden sich in den verschiedensten Systemen vom Isolator über die Halbleiter bis hin zu Metallen. In dieser Arbeit werden die durch …

Electronic structure of strongly correlated low-dimensional spin ½ systems: cuprates and vanadates
In the first two chapters we presented the basics of density functional theory and semiempirical LSD+U approximation, which was implemented in the full-potential local-orbital (FPLO) minimal-basis calculation scheme. In the third chapter we tested the implemented version of LSDA+U on 3d …
