Covalent bonding and hybridization effects in the corundum-type transition-metal oxides V2O3 and Ti2O3
V. Eyert, U. Schwingenschloegl, U. Eckern
The electronic structure of the corundum-type transition-metal oxides V2O3 and Ti2O3 is studied by means of the augmented spherical wave method, based on density-functional theory…
Bosonization of dimerized Hubbard chains
C. Mocanu, M. Dzierzawa, P. Schwab +1
The role of Klein factors is investigated for the bosonized Hamiltonian of the dimerized Hubbard model. Contrary to previous approaches we take into account their number changing p…
Superconductor-Ferromagnet Bi-Layers: a Comparison of s-Wave and d-Wave Order Parameters
T. Lueck, U. Eckern
We study superconductor-ferromagnet bi-layers, not only for s-wave but also for d-wave superconductors. We observe oscillations of the critical temperature when varying the thickne…
