Small Fermi surface in the one-dimensional Kondo lattice model
J. C. Xavier, E. Novais, E. Miranda
We study the one-dimensional Kondo lattice model through the density matrix renormalization group (DMRG). Our results for the spin correlation function indicate the presence of a s…

A Coulomb gas approach to the anisotropic one-dimensional Kondo lattice model at arbitrary filling
E. Novais, E. Miranda, A. H. Castro Neto +1
We establish a mapping of a general spin-fermion system in one dimension into a classical generalized Coulomb gas. This mapping allows a renormalization group treatment of the anis…
