Valence transition and superconductivity in the extended periodic Anderson model
In this thesis, an extended periodic Anderson model with an additional local Coulomb repulsion U f c between localized f electrons and conduction electrons is investigated by use of the projector-based renormalization method (PRM). First, it is shown that the model in one dimension shows a valence …

Besetzte und unbesetzte elektronische Struktur von geordneten Dünnschichtverbindungen der Seltenen Erden Eu und Yb mit den Übergangsmetallen Pd und Ni
The present thesis deals with the occupied and unoccupied electronic states of intermetallic compounds of the rare-earth metals (RE) Eu and Yb with the transition metals Pd and Ni. The compounds were prepared in-situ as epitaxial thin films on single-crystalline substrates. For comparison, the …
