TL;DR: In this article, the partial density of state obtained from local density approximation (LDA) and U$ calculations were compared with the experimental results, and the LDA+U$ approach was suitable to correct LDA self-interaction error of the cation $d$ states.

TL;DR: In this article, soft X-ray absorption spectroscopy (SXAS) was used to study the redox behavior of vanadium oxide (Na−VOx) nanotubes in a rechar...

TL;DR: High-resolution polarization-dependent resonant inelastic x-ray scattering (RIXS) at the O K resonance of NiO showing a rich excitation spectrum and pointing out that O K RIXS of correlated metal oxides allows a quantitative and consistent determination of the charge transfer energy delta and the Hund coupling energy J(H).

TL;DR: Polarized resonant x-ray fluorescence spectroscopy at O $1s$ resonances was used to study ${\mathrm{CuGeO}}_{3}.$ Two distinct spectral contributions are identified, i.e., an intense ''main band'' of soft-x-ray fluorescent, reflecting primarily bandlike 2p$ states, and resonant inelastic xray scattering (RIXS) characterized by spectral features that disperse linearly with excitation energy and resonate at the pre-edge peak as mentioned in this paper.

TL;DR: It is shown that the present LDACU SIC calculation approach is suitable to correct the LDA self-interaction error of the cation d-states, and selected excitations to the Zn 3d, 4s and 4p states, hybridized with O 2p states.
