Strong electronic correlations are often associated with the proximity of a Mott-insulating
state. In recent years however, it has become increasingly clear that the Hund's rule …

A review of the basic ideas and techniques of the spectral density-functional theory is
presented. This method is currently used for electronic structure calculations of strongly …

The calculation of the electronic properties of materials is an important task of solid-state
theory, albeit particularly difficult if electronic correlations are strong, eg, in transition metals …

We study the interplay of crystal field splitting and Hund coupling in a two-orbital model
which captures the essential physics of systems with two electrons or holes in the eg shell …

A versatile method for combining density functional theory in the local density approximation
with dynamical mean-field theory (DMFT) is presented. Starting from a general basis …

The interplay of spin–orbit coupling and Coulomb correlations has become a hot topic in
condensed matter theory and is especially important in 4d and 5d transition metal oxides …

The very first dynamical implementation of the combined GW and dynamical mean-field
scheme “GW+ DMFT” for a real material was achieved recently [Tomczak, Europhys. Lett …

We employ a combination of chemical substitution and angle resolved photoemission
spectroscopy to prove that the Fermi level in the γ band of Sr 2-y La y RuO 4 can be made to …

We investigate a quarter-filled two-band Hubbard model involving a crystal-field splitting,
which lifts the orbital degeneracy as well as an interorbital hop** (interband hybridization) …

We propose a refined scheme of deriving an effective low-energy Hamiltonian for materials
with strong electronic Coulomb correlations beyond density functional theory (DFT). By …
