Friedel oscillations in one-dimensional metals: From Luttinger`s theorem to the Luttinger liquid
(ELSEVIER SCIENCE BV, 2008)
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 ...
Friedel oscillations in a Luttinger liquid with long-range interactions
(American Physical Society, 2001-06)
We introduce a path-integral approach that allows us to compute charge-density oscillations in a Luttinger liquid with impurities. We obtain an explicit expression for the envelope of Friedel oscillations in the presence ...

Origem dos momentos magnéticos localizados em ligas de cromo com metais de transição por oscilações de Friedel
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Física - PPGF, 2006-08-02)
The fundamental magnetic properties of chromium and its alloys Cr(1¡x)Nb(x) and Cr(1¡x)V(x), were investigated with the aim to achieve a better comprehension about the nature of the spin density waves. Was dened the edge ...
Scanning tunneling microscope operating as a spin diode
(Amer Physical Soc, 2011-09-19)
We theoretically investigate spin-polarized transport in a system composed of a ferromagnetic scanning-tunneling-microscope (STM) tip coupled to an adsorbed atom (adatom) on a host surface. Electrons can tunnel directly ...
Quantum Ripples in Strongly Correlated Metals

DC voltage profile of a 1D pumped wire with two dynamical and one static impurities
(Elsevier Science, 2009-10)
In this work we study the behavior of the voltage profile of a 1D quantum wire with an impurity when transport is induced by two ac voltages that oscillating with a phase lag define a quantum pump. The voltage profile ...
