Dash AU - Fabien Bruneval AU - Trinite V AU - N Vast AU - Lucia Reining AB - We address the question of the prediction and interpretation of experimental spectra obtained by the excitation of valence electrons, such as valence photoemission spectra, Bremsstrahlung isochromat spectra (BIS), electron energy-loss spectra (EELS) or absorption spectra using ab initio methods. We discuss which levels of theory are appropriate for which experiment, from ground-state density-functional calculations to the random phase approximation and time-dependent density-functional methods, and also discuss many body effects in the quasiparticle framework. We show applications of these methods to three different transition-metal oxide systems: ZrO2, TiO2 and Cu2O. (c) 2006 Elsevier B.V. All rights reserved. BT - Comp. Mat.
