A canonical transformation is used to relate the Anderson model of a localized magnetic moment in a dilute alloy to that of Kondo. In the limit of small $s\ensuremath{-}d$ mixing, which is the most favorable case for the occurrence of a moment, the two models are shown to be equivalent. The Anderson model thus has low-temperature anomalies similar to those previously discussed for the Kondo model. 
On the symmetric Anderson model for a magnetic impurity and on Mattis' model
Abstract Recent work on the symmetric Anderson model is discussed critically. Objections against theories used in the LSF-and Kondo-regime are ruled out by showing that relevant quantities depend on
PERTURBATIVE RESULT OF TWO-IMPURITY ANDERSON MODEL IN THE KONDO LIMIT
Abstract The magnetic susceptibility of the two-impurity Anderson model in the Kondo limit is calculated to fourth order in coupling constant J . Results are presented for three different regimes
Narrow band limit of the equivalence between Anderson and Kondo Hamiltonians
Abstract It is shown that for a narrow band version of the Anderson Hamiltonian, the transformation of Schrieffer and Wolff can be carried out to all orders in the mixing parameter. The resulting
On the limits of application of Anderson and Kondo models in physics of strongly correlated electron systems
We argue that the Anderson and Kondo models turn out to be irrelevant for the description of some strongly correlated electron systems and suggest the mechanism for the formation of many-body states
Local Density of States in the Antiferromagnetic and Ferromagnetic Kondo Models
Based on a simple approximation scheme we have computed the local density of states (LDOS) of the antiferromagnetic and ferromagnetic Kondo models for the full range of band occupations and coupling
A note on the equivalence of the anderson and s-d hamiltonians
Abstract It is shown that if the conduction band is effectively narrow, and |;ϵ d |; and U of the Anderson model are large then for values of w close to the Fermi energy the hierarchy of Anderson
Density of states for the Anderson model
The Anderson model is studied in the limit U to infinity using a Green function decoupling procedure. It is shown that the solution gives the correct results in the intermediate valence case, and in
Low-temperature thernodynamics of the Anderson model. I. Symmetric case
Abstract The thermodynamics of the Anderson model describing the formation of localized magnetic moments in a metal is presented on the basis of the exact solution. In the symmetric case a
Thermodynamical properties of the Anderson model in the atomic limit
Abstract The theoretical trend of the specific heat, the static magnetic susceptibility and the valence of the localized electrons in the atomic limit of the Anderson model has been investigated. The
Finite-temperature properties of the two-orbital Anderson model
The metallic phase of the two-orbital Anderson lattice is studied in the limit of infinite spatial dimensions, where a second-order perturbation treatment is used to solve the single-site problem.
