Mott-Hubbard exciton in the optical conductivity of YTiO3 and SmTiO3
A. Gössling, R. Schmitz, H. Roth +5
In the Mott-Hubbard insulators YTiO3 and SmTiO3 we study optical excitations from the lower to the upper Hubbard band, d^1d^1 -> d^0d^2. The multi-peak structure observed in the op…
Insulator-Metal transition in the Doped 3d1 Transition Metal Oxide LaTiO3
L. Craco, M. S. Laad, S. Leoni +1
The doping induced insulator-metal transition in is studied using the ab-initio LDA+DMFT method. Combining the LDA bandstructure for the actual, distorted s…
On the heavy-fermion behavior of the pyrochlore transition-metal oxide
M. S. Laad, L. Craco, E. Müller-Hartmann
Motivated by the heavy fermion Fermi liquid (HFFL) features observed at low- in the pyrochlore , we consider a material-specific model that includes aspects of the…
Derivation of effective spin models from a three band model for CuO_2-planes
E. Müller-Hartmann, A. Reischl
The derivation of effective spin models describing the low energy magnetic properties of undoped CuO_2-planes is reinvestigated. Our study aims at a quantitative determination of t…
On the Origin of the Non-Fermi Liquid Behavior of SrRuO_{3}
M. S. Laad, E. Müller-Hartmann
Motivated by the unusual features observed in the transport properties of the ferromagnetic "bad metal" , we construct a model incorporating essential features of the re…
Orbital Correlations in the Ferromagnetic Half-Metal $CrO_{2}
M. S. Laad, L. Craco, E. Müller-Hartmann
We deduce a model relevant for the description of the ferromagnetic half-metal Chromium dioxide (), widely used in magnetic recording technology. The model describes the e…
