抄録

The crystal-field effects on the periodic Anderson model are investigated by means of the Gutzwiller approximation. The effective mass, the spin susceptibility and the generalized charge susceptibilities are numerically evaluated in the Kondo regime for three different kinds of simple level schemes. It is shown that former two quantities are considerably enhanced as the crystal-field splitting is increased. In the sufficiently large splitting regime, the analytic expression for the mass-enhancement factor is obtained, which is similar to that for the Kondo temperature in the impurity Anderson model.
