The availability of X‐ray light sources with increased resolution and intensity has provided a
foundation for increasingly sophisticated experimental studies exploiting the spectroscopy of …

The emergence of state-of-the-art X-ray light sources has paved the way for novel
spectroscopies that take advantage of their atomic specificity to shed light on fundamental …

Recent advances in X-ray sources have led to a renaissance in spectroscopic techniques in
the X-ray region. These techniques that involve the excitation of core electrons can provide …

We review methods to compute X-ray absorption spectra (XAS) with special focus on the
transition-potential approach of Triguero et al.[Phys. Rev. B 58 (1998) 8097] and its …

For electronic excitations in the ultraviolet and visible range of the electromagnetic spectrum,
the intensities are usually calculated within the dipole approximation, which assumes that …

The C 1s and N 1s near-edge x-ray absorption fine structure (NEXAFS) spectra of three
prototype tetraphenyl porphyrin (TPP) molecules are discussed in the framework of a …

The calculation of X-ray emission spectroscopy with equation of motion coupled cluster
theory (EOM-CCSD), time-dependent density functional theory (TDDFT), and resolution of …

The accuracy of non-resonant and resonant (resonant inelastic X-ray scattering) X-ray
emission spectra simulated based upon Kohn-Sham density functional theory is assessed …

The computational cost of calculations of K-edge X-ray absorption spectra using time-
dependent density functional (TDDFT) within the Tamm–Dancoff approximation is …

This paper presents accurate numerical solutions for nonlinear eigenvalue analysis of three-
dimensional acoustic cavities by boundary element method (BEM). To solve the nonlinear …
