We take as granted Anderson's statement that in the low-temperature limit the usual Kondos-d model evolves toward a fixed point in which the effective exchange coupling of the impurity with the conduction electrons is infinitely strong. The low-temperature properties (T«TK) are then described phenomenologically in the same spirit as the usual Landau theory of Fermi liquids. The specific heat, spin susceptibility, and resistivity are expressed in terms of a small number of numerical parameters… 
Hamiltonian theory of the strongly coupled limit of the Kondo problem in the overscreened case
By properly generalizing Nozieres' Fermi liquid theory, we construct a Hamiltonian approach to the scattering of conduction electrons off a spin-1/2 impurity in the overscreened Kondo regime as . We
Non-Fermi Liquid Behavior in Kondo Models
Despite the fact that the low energy behavior of the basic Kondo model cannot be studied perturbatively it was eventually shown by Wilson, Anderson, Nozieres and others to have a simple “local Fermi
Mesoscopic fluctuations in the Fermi-liquid regime of the Kondo problem
We consider the low temperature regime of the mesoscopic Kondo problem, and in particular the relevance of a Fermi-liquid description of this regime. Mesoscopic fluctuations of both the quasiparticle
Intersite coupling effects in a kondo lattice.
TLDR
Observations indicate that the screening of the magnetic moments in the lattice involves antiferromagnetic intersite correlations with a larger energy scale in comparison with the Kondo impurity case.
Resistivity cross-over for the non-degenerate Anderson model
Abstract One of the most difficult quantities to calculate for the non-degenerate Anderson and Kondo models has been the resistivity in the cross-over region between the low-temperature Fermi liquid
Alternative renormalisation in the Kondo problem
Whereas the standard expansion of the 'quantum field theory' belonging to the s-d exchange Kondo Hamiltonian for a spin impurity in a paramagnetic host metal describes the high-energy scattering, the
Fermi-liquid theory for SU ( N ) Kondo model
We extend the Fermi liquid theory of Nozi\`eres by introducing the next-to-leading order corrections to the Fermi liquid fixed point. For a general $\text{SU}(N)$ Kondo impurity away from

Relation between the anomalous resistivity and the susceptibility for dilute magnetic alloys
It follows from scattering theory that the anomalous resistivity of dilute magnetic impurities may be written as Δρ=A−B cos 2S(π/5), whereS is a temperature-dependent spin value. This relation is
