Bethe-Ansatz Solution of the Degenerate Anderson Model: Applications to Ce and Yb Impurity Systems

Part of the Springer Series in Solid-State Sciences book series (SSSOL, volume 62)

Abstract

We review the Bethe-ansatz solution of the orbitally degenerate Anderson model for a magnetic impurity in a metal. The groundstate properties of the integer and mixed-valent impurity are discussed in the presence of external potentials, e.g. magnetic and crystalline fields, and with spin-orbit coupling. The thermodynamic Bethe-ansatz equations are reviewed and their solution for Ce and Yb impurities are compared with experimental data. The Bethe ansatz solution, the groundstate properties and the thermodynamics of a model for a mixed-valent impurity with two magnetic configurations are presented. This model is supposed to resemble some of the properties of Tm-ions.
