dc.descriptionWe study the one-dimensional Kondo lattice model through the density-matrix renormalization group. Our results for the spin-correlation function indicate the presence of a small Fermi surface in large portions of the phase diagram, in contrast to some previous studies that used the same technique. We argue that the discrepancy is due to the open boundary conditions, which introduce strong charge perturbations that strongly affect the spin Friedel oscillations.
