The question of whether the Anderson–Mott localization enhances or reduces magnetic
correlations is central to the physics of magnetic alloys. Particularly intriguing is the case of …

Narrow band materials (transition metals and rare‐earth elements compounds) often reveal
anomalous physical properties. Their electronic structure is strongly renormalized by …

We present an efficient and numerically stable algorithm for calculation of two-particle
response functions within the dynamical mean-field theory. The technique is based on …

Several new aspects of the subtle interplay between electronic correlations and disorder are
reviewed. First, the dynamical mean-field theory (DMFT) together with the geometrically …

The dynamical mean-field theory (DMFT) is a widely applicable approximation scheme for
the investigation of correlated quantum many-particle systems on a lattice, eg, electrons in …

Strongly correlated fermions in a crystal or in an optical lattice in the presence of binary-alloy
disorder are investigated. We employ the statistical dynamical mean-field theory, which …

Motivated by the recent proposal that the Monte Carlo sign problem might be used as an
indicator of quantum phase transitions, we simulate the periodic Anderson model at half …

First-principles band structure theory on the basis of the density functional theory (DFT)
plays an essential role in the investigation of topological properties of weakly-correlated …

In this work we investigated structural, magnetic and transport properties of La 0.70 Sr 0.21
K 0.09 MnO 3 compound produced by the standard sol–gel route. The crystal structure was …

The Kondo lattice model with substitutional disorder is studied with attention to the size of
the Fermi surface and the associated Dingle temperature. The model serves for …
