Recent experiments by Larson et al. [Phys. Rev. Lett. 99, 026401 (2007)] demonstrate the feasibility of measuring local $d\char21{}d$ excitations using nonresonant inelastic x-ray scattering (IXS). We establish a general framework for the interpretation where the $d\char21{}d$ transitions created in the scattering process are expressed in effective one-particle operators that follow a simple selection rule. The different operators can be selectively probed by employing their different…

Resonant Inelastic X-ray Scattering Studies of Elementary Excitations
In the past decade, resonant inelastic x-ray scattering (RIXS) has made remarkable progress as a spectroscopic technique. This is a direct result of the availability of high-brilliance synchrotron
Theoretical approach to direct resonant inelastic x-ray scattering on magnets and superconductors
The capability to probe the dispersion of elementary spin, charge, orbital, and lattice excitations has positioned resonant inelastic x-ray scattering (RIXS) at the forefront of photon science. In
Quanty for core level spectroscopy - excitons, resonances and band excitations in time and frequency domain
Depending on the material and edge under consideration, core level spectra manifest themselves as local excitons with multiplets, edge singularities, resonances, or the local projected density of
Resonant X-ray Scattering and Orbital Degree of Freedom in Correlated Electron Systems
The resonant X-ray scattering (RXS) and the resonant inelastic X-ray scattering (RIXS) in correlated electron systems with the orbital degree of freedom are reviewed from the theoretical view points.
Full-Potential Simulation of X-ray Raman Scattering Spectroscopy.
This work presents a new ab initio way to calculate X-ray Raman scattering spectra within the independent electron approximation and shows that the momentum transfer dependence in two typical cases, the F K-edge in LiF and the B and N K-edges in hexagonal BN, is well-reproduced.
Multiplet ligand-field theory using Wannier orbitals
We demonstrate how ab initio cluster calculations including the full Coulomb vertex can be done in the basis of the localized, generalized Wannier orbitals which describe the low-energy density
Temperature dependence of crystal field excitations in CuO.
The spectra broaden considerably with increasing temperature, consistently with an enhancement of the coupling between crystal field excitations and the temperature-dependent continuum of states above the band gap.
