Theoretical description of optical and X-ray absorption spectra of MgO including many-body effects
Vijaya Begum, Markus E. Gruner, Christian Vorwerk +2
Here we report the optical and x-ray absorption (XAS) spectra of the wide-band-gap oxide MgO using density functional theory (DFT) and many-body perturbation theory (MBPT). Our com…
Influence of Polymorphism on the Electronic Structure of GaO
Jack E. N. Swallow, Christian Vorwerk, Piero Mazzolini +21
The search for new wide band gap materials is intensifying to satisfy the need for more advanced and energy efficient power electronic devices. GaO has emerged as an altern…
Excitation Pathways in Resonant Inelastic X-Ray Scattering of Solids
Christian Vorwerk, Francesco Sottile, Claudia Draxl
We present a novel derivation of resonant inelastic x-ray scattering (RIXS) which yields an expression for the RIXS cross section in terms of emission pathways between intermediate…
