Ab initio wavefunction based methods for excited states in solids: correlation corrections to the band structure of ionic oxides
L. Hozoi, U. Birkenheuer, P. Fulde +2
Ab initio wavefunction based methods are applied to the study of electron correlation effects on the band structure of oxide systems. We choose MgO as a prototype closed-shell ioni…

A simplified method for the computation of correlation effects on the band structure of semiconductors
Uwe Birkenheuer, Peter Fulde, Hermann Stoll
We present a simplified computational scheme in order to calculate the effects of electron correlations on the energy bands of diamond and silicon. By adopting a quasiparticle pict…
