Instability of the Fermi-liquid fixed point in an extended Kondo model
M. Lavagna, A. Jerez, D. Bensimon
We study an extended SU(N) single-impurity Kondo model in which the impurity spin is described by a combination of Abrikosov fermions and Schwinger bosons. Our aim is to describe b…

Antiferromagnetism of almost localized fermions: Evolution from Slater-type to Mott-Hubbard gap
P. Korbel, W. Wójcik, A. Klejnberg +3
We supplement (and critically overview) the existing extensive analysis of antiferromagnetic solution for the Hubbard model with a detailed discussion of two specific features, nam…
