Commensurability Transition and Stripe Phases in the Ginzburg-Landau Theory
B. Uchoa, G. G. Cabrera
We phenomenologically describe the thermodynamics of charge and spin density waves in doped high- oxides. We have explicitly calculated stable non-homogeneous solutions in t…

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…

Phase diagram of the anisotropic Kondo chain
E. Novais, E. Miranda, A. H. Castro Neto +1
We establish the phase diagram of the one-dimensional anisotropic Kondo lattice model at T=0 using a generalized two-dimensional classical Coulomb gas description. We analyze the p…
