Systematic Mapping of the Hubbard Model to the Generalized t-J Model

Alexander Reischl, Erwin Müller-Hartmann, Götz S. Uhrig

The generalized t-J model conserving the number of double occupancies is constructed from the Hubbard model at and in the vicinity of half-filling at strong coupling. The construct…

Orbital Kondo Effect in : A LSDA+DMFT Study

L. Craco, M. S. Laad, E. Müller-Hartmann

Motivated by a collection of experimental results indicating the strongly correlated nature of the ferromagnetic metallic state of , we present results based on a combinat…

On the Normal State Electronic properties of Layered Sr_2 RuO_4

M. S. Laad, E. Müller-Hartmann

Based on a comprehensive perusal of experimental results, we construct a microscopic model describing the normal state of layered 4d oxide Sr_2 RuO_4 incorporating relevant quantum…

Dynamical correlations in half-metallic manganites

L. Craco, M. S. Laad, E. Müller-Hartmann

Motivated by the recent optical and photoemission measurements on half-metallic ferromagnetic three-dimensional manganites, we combine a tight-binding fit of the one-particle bands…

Optical and Magneto-optical Response of a Doped Mott Insulator

Mukul S. Laad, Luis Craco, E. Müller-Hartmann

We study the optical, Raman, and ac Hall response of the doped Mott insulator within the dynamical mean-field theory () for strongly correlated electron systems. The occu…
