Exact Solution of the Anderson Model and Its Thermodynamics II — Including Crystalline Field and Spin-Orbit Coupling

Abstract

The thermodynamic properties of the highly correlated degenerate Anderson model are discussed on the basis of the Bethe-ansatz method, in the presence of the crystalline field and the spin-orbit coupling. The properties of the specific heat are investigated in detail, as a typical example, for the case of Ce impurities in a cubic crystalline field. The analytic expressions are given for the Fermi-liquid relation, the coefficient of the T-linear specific heat and the effective Kondo temperature. The curve of the temperature-dependent specific heat is shown to become asymmetric and have a shoulder structure when the splitting of the crystalline field is increased.KeywordsAnderson ModelCharge FluctuationKondo TemperatureCrystalline FieldSpecific Heat CurveThese keywords were added by machine and not by the authors.
