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…
Finite-Size Bosonization and Self-Consistent Harmonic Approximation
C. Mocanu, M. Dzierzawa, P. Schwab +1
The self-consistent harmonic approximation is extended in order to account for the existence of Klein factors in bosonized Hamiltonians. This is important for the study of finite s…
Charge order, orbital order, and electron localization in the Magneli phase Ti4O7
V. Eyert, U. Schwingenschloegl, U. Eckern
The metal-insulator transition of the Magneli phase Ti4O7 is studied by means of augmented spherical wave (ASW) electronic structure calculations as based on density functional the…
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…
