Momentum-dependent resonant inelastic X-ray scattering at the Si K edge of 3C-SiC: A theoretical study on a relation between spectra and valence band dispersion
Yunori Nisikawa, Muneharu Ibuki, Manabu Usuda
We theoretically demonstrate that a resonant inelastic x-ray scattering (RIXS) with a sizable momentum transfer can be utilized to study valence band dispersion for broad band mate…
Anisotropy of Resonant Inelastic X-Ray Scattering at the K Edge of Si:Theoretical Analysis
Yunori Nisikawa, Manabu Usuda, Jun-ichi Igarashi
We investigate theoretically the resonant inelastic x-ray scattering (RIXS) at the edge of Si on the basis of an ab initio calculation. We calculate the RIXS spectra with syste…
An ab-initio calculation of magnetic resonant x-ray scattering spectra in NiO
Manabu Usuda, Manabu Takahashi, Jun-ichi Igarashi
We investigate the magnetic resonant x-ray scattering spectra around the edge of Ni in antiferromagnetic NiO using an \textit{ab-initio} band-structure calculation based on the…
Resonant Inelastic X-Ray Scattering at the K Edge of Ge
Yunori Nisikawa, Manabu Usuda, Jun-ichi Igarashi +2
We study the resonant inelastic x-ray scattering (RIXS) at the edge of Ge. We measure RIXS spectra with systematically varying momenta in the final state. The spectra are a mea…
Magnetic Resonant X-Ray Scattering in KCuF3
M. Takahashi, M. Usuda, J. Igarashi
We study the magnetic resonant x-ray scattering (RXS) spectra around the edge of Cu in KCuF on the basis of an {\em ab initio} calculation. We use the full-potential linear…
All-electron GW calculation based on the LAPW method: application to wurtzite ZnO
Manabu Usuda, Noriaki Hamada, Takao Kotani +1
We present a new, all-electron implementation of the GW approximation and apply it to wurtzite ZnO. Eigenfunctions computed in the local-density approximation (LDA) by the full-pot…
