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…
