Abstract

A recently developed method based on projection techniques is applied to the computation of electron correlations in excited states of semiconductors. In particular it is shown that the method is able to reproduce the results previously obtained by applying the variational Local Ansatz. The advantages of the present approach are its conceptual simplicity and that it can be applied not only to weakly but also to strongly correlated electronic systems.
