(color online) Physical quantities as a function of V when E f = − 1 at different fillings. Contributions of the conduction c orbitals and localized f orbitals to (a) the magnetic moment and (c) the number of electrons. The labels are the same as those in Fig. (a), except that the blue dashed line with solid (hollow) circles is the contributions from the f orbital (c orbital) at filling n=1.75 when the cluster size is 1 × 2. (b) The correlation function between two neighboring f orbitals, C ff ( r = 1 ) . (d) The on-site f and c orbital correlation, C fd ( r = 0 ) . The blue dashed line with solid circles is the results from filling n=1.75 when the cluster size is 1 × 2. The rest of the labels are the same as those in Fig. 2(b).
