Exact Stripe, Checkerboard and Droplet Ground States in Two Dimensions
Zsolt Gulácsi,Miklos Gulacsi +1 more
TL;DR: In this paper, a generalized periodic Anderson model is used to obtain exact static non-degenerate stripe and checkerboard ground states in a two-dimensional generalized periodicAnderson model, for a broad concentration range below quarter filling.

Hole doping and disorder effects on the one-dimensional Kondo lattice, for ferromagnetic Kondo couplings
TL;DR: In this paper, the authors investigated the one-dimensional Kondo lattice model for ferromagnetic Kondo couplings and showed that the Anderson localization inevitably takes place in that weak-coupling Haldane system, by the introduction of quenched randomness.

Slave fermions and the Anderson lattice—ferromagnetism for low electron count in one and two dimensions
TL;DR: In this paper, the slave-fermion representation of strongly correlated electrons was applied to the spin-1 2 infinite-U Anderson lattice near quarter-filling, and the hybridization and f-level dependence of this critical electron count for the full range of valence was investigated.

Magnetic susceptibility of mixed-valence rare-earth compounds
Chandra Varma,Y. Yafet +1 more
TL;DR: In this paper, the Anderson model was applied to rare earth compounds and the effect of temperature-independent magnetic susceptibility at low temperatures in their mixed valence phase was examined for an isolated impurity.
Fermi-liquid versus non-Fermi-liquid behaviour
TL;DR: In this paper, the properties of the three-dimensional and one-dimensional conductors are compared, and a comprehensive description of the bosonization technique is presented for the two-dimensional systems.
Weak ferromagnetism with the Kondo screening effect in the Kondo lattice systems
Yu Liu,Guang-Ming Zhang,Lu Yu +2 more
TL;DR: In this article, the interplay between ferromagnetism and the Kondo screening effect in the conventional Kondo lattice systems at finite temperatures has been investigated within an effective mean-field theory for small conduction electron densities.
