Abstract

Band calculation for a series of Ce pnictides is carried out on the basis of dynamical mean field theory (DMFT). The auxiliary impurity problem is solved by a method named NCAf^2vc, which includes the correct exchange process of the f^1→f^0,f^2 virtual excitation. The splitting of the self-energy due to the spin-orbit interaction and the crystalline field effect is also considered. The systematics of the single-particle spectrum (SGS) such as the double-peak structure, show good correspondence with the experimental results of photoemission spectra (PES) at higher temperatures. At low temperatures, two types of solutions appear: one has an appreciable Kondo resonance peak at the Fermi energy and the other does not. The former leads to the metallic state and the latter to the localized state of the f electron with the Fermi surface of the La pnictides type. When the occupation number of (j=5/2)Γ_8 is large, the wave-number dependence of the 4f SGS becomes appreciable, while it is very weak in the (j=5/2)Γ_7-dominant occupation case. The angle-resolved PES, which is similar to that obtained from of experiments on CeP, is obtained in the Γ_8-dominant case. The valence-fluctuation-like state is expected in CeN.
