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…
Dimerization induced by the RKKY interaction
J. C. Xavier, R. G. Pereira, E. Miranda +1
We report the presence of spin dimerization in the ground state of the one dimensional Kondo lattice model at quarter filling. The emergence of this new phase of the Kondo lattice…
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…
Luttinger liquid superlattices: realization of gapless insulating phases
J. Silva-Valencia, E. Miranda, Raimundo R. dos Santos
We investigate Luttinger Liquid superlattices, a periodic structure composed of two kinds of one-dimensional systems of interacting electrons. We calculate several properties of th…
