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 …

The Hubbard model accounts for many of the diverse phenomena observed in solid-state
materials, despite incorporating only nearest-neighbour hopping and on-site interactions for …

Abstract Alkali-doped fullerides (${{A} _ {3}}{{\text {C}} _ {60}} $ with A= K, Rb, Cs) show a
surprising phase diagram, in which a high transition-temperature (${{T} _ {\text {c}}} $) s …

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 present an approach that combines the local-density approximation (LDA) and the
dynamical mean-field theory (DMFT) in the framework of the full-potential linear augmented …

A single-site dynamical mean-field study of a three band model with the rotationally invariant
interactions appropriate to the t 2 g levels of a transition metal oxide reveals a quantum …

Alkali-doped fullerides A 3C60 (A= K, Rb, Cs) are surprising materials where conventional
phonon-mediated superconductivity and unconventional Mott physics meet, leading to a …

The bad-metal behavior of the iron pnictides has motivated a theoretical description in terms
of a proximity to Mott localization. Since the parent compounds of the iron pnictides contain …

We give an elementary introduction to a recent diagrammatic extension of dynamical mean
field theory (DMFT) coined dynamical vertex approximation (DΓA). This approach contains …

We present an implementation of the hybridization expansion impurity solver which employs
sparse-matrix exact-diagonalization techniques to compute the time evolution of the local …
