The electronic structures of uranium-based compounds have been studied by photoelectron
spectroscopy with soft X-ray synchrotron radiation. Angle-resolved photoelectron …

It is shown that the large-N approach yields two energy scales for the Kondo lattice model.
The single-impurity Kondo temperature, TK, signals the onset of local singlet formation …

The so called exhaustion problem occurs when few electrons have to screen many spins in
a metal with magnetic impurities. A singlet Fermi liquid ground state is possible only if all …

The hybridization between localized 4 f electrons and itinerant electrons in rare-earth-based
materials gives rise to their exotic properties like valence fluctuations, Kondo behaviour …

Wilson's numerical renormalization-group method is used to study the paramagnetic ground
state of the periodic Anderson model within the dynamical mean-field approach. For the …

Resonant inelastic x-ray scattering (RIXS) yields clear evidence of spectroscopic Kondo
scales in heavy fermions. In YbInCu 4 and YbAgCu 4 RIXS probes the Yb 2+ component of …

The electronic structure of the first reported heavy fermion compound without f electrons, LiV
2 O 4, was studied by an ab initio calculation method. As a result of the trigonal splitting and …

The k-resolved single particle excitations, as determined by angle-resolved photoemission
spectroscopy (ARPES), are compared and contrasted for, LaRu2Si2, CeRu2Si2, ThRu2Si2 …

Over the last 25 years, dynamical mean-field theory (DMFT) has emerged as one of the most
powerful new developments in many-body physics. Written by one of the key researchers in …
