We introduce an extension of the dynamical mean-field approximation (DMFA) that retains
the causal properties and generality of the DMFA, but allows for systematic inclusion of …

Handbook on the Physics and Chemistry of Rare Earths: Including Actinides is a continuous
series of books covering all aspects of rare earth science, including chemistry, life sciences …

We present numerically exact predictions of the periodic and single impurity Anderson
models to address photoemission experiments on heavy fermion systems. Unlike the single …

Photoemission spectra measured with an energy resolution of 5 meV from Ce-based heavy
fermion materials are presented. The spectra add strong support to the interpretation of the …

The mixed-valent compound EuNi 2 P 2 was studied by photoemission. Observed splittings
and dispersions of the Eu 4 f 6 final state close to energy crossings of the Eu 4 f and Ni 3 d …

The electronic properties of the Yb compounds YB Cu 2 Si 2, YBAg Cu 4, and Yb Al 3 along
with purely divalent Yb metal, have been investigated by means of high-resolution ultraviolet …

In order to elucidate the temperature‐dependent occupancy number of Ce 4 f electrons and
valence state of Ce ions in cerium mononitride (CeN), we perform an ab initio calculation by …

We present temperature-dependent photoemission (PES) measurements on single-
crystalline YbInCu 4, a stoichiometric material that shows an isostructural first-order valence …

In order to investigate the structure-dependent correlation strength and occupation number
of 4f electrons in cerium monoarsenide (CeAs) with the NaCl-type (B1-type) and CsCl-type …

The electrical resistivity of the SmxMn1− xS (0.15≤ x≤ 0.25) solid solutions in the
temperature range of 80–300 K was measured. Minimum and maximum in the temperature …
