Calculations of ground-state and excited-state properties of materials have been one of the major goals of condensed matter physics. Ground-state properties of solids have been extensively investigated for several decades within the standard density functional theory. Excited-state properties, on the other hand, were relatively unexplored in ab initio calculations until a decade ago. The most suitable approach up to now for studying excited-state properties of extended systems is the Green… Expand

A new method to extract excitation energies directly from the quasi-particle energies based on the GW approximation is developed and is shown to outperform the time-dependent density functional theory (TDDFT) and are comparable with higher level excited state calculations, including the equation-of-motion couple cluster (EOM-CC) theory and the BSE, but with less computational effort.

The one-electron excitation spectra of ferromagnetic nickel have been obtained from a first-principles calculation of the self-energy operator within the so-called GW approximation and a significant contribution to the spectral weight from quasiparticle peaks around that energy is found. Expand
