Abstract
Recent band calculations for Ce compounds based on the dynamical mean field theory (DMFT) are reported. The auxiliary impurity problem has been solved by a method named NCAf(2)vc, which includes the correct exchange process of the [Formula: see text] virtual excitation, the crystalline field splitting (CFS), and the spin-orbit interaction (SOI) of the self-energy. These are necessary features in the quantitative band theory for Ce compounds. The results of applications on Ce metal and Ce-monopnictides are presented.
