Friedel oscillations in one-dimensional metals: from Luttinger's theorem to the Luttinger liquid
arXiv:0710.0358 · doi:10.1016/j.jmmm.2008.02.077
Abstract
Charge density and magnetization density profiles of one-dimensional metals are investigated by two complementary many-body methods: numerically exact (Lanczos) diagonalization, and the Bethe-Ansatz local-density approximation with and without a simple self-interaction correction. Depending on the magnetization of the system, local approximations reproduce different Fourier components of the exact Friedel oscillations.
