We investigate the two-orbital periodic Anderson model with f 2 -configuration by using the dynamical mean-field theory in which the effective impurity Anderson model is solved using the exact diagonalization method. The renormalization factor Z and the local moment hS 2 i are obtained as functions

We have made ultrasonic measurements on a filled skutterudite PrOs 4 Sb 12 showing a heavy Fermion superconductivity at T C ¼ 1:85 K: The elastic constants ðC 11 À C 12 Þ=2 and C 44 of PrOs 4 Sb 12 exhibit low-temperature softenings below 20 K down to T C ; indicating a quadrupole fluctuation of Pr
The periodic Anderson model with negative correlation energy ( -Cl, U>O) has been used to investigate the effective mass and the electronic specific heat in the normal state. The mean occupation number of the local electrons has been treated in a selfconsistent method. Numerical calculation shows th
