Friedel Oscillations in Luttinger Liquids Reinhold Egger and Hermann Grabert
We study the density disturbance of a correlated one–dimensional electron liquid in the presence of a scatterer or a barrier. The 2kF – periodic density profile away from the barrier (Friedel oscillation) is computed for arbitrary electron–electron interaction and arbitrary impurity strength. We find that in presence of correlations, the Friedel oscillation decays slower than predicted by Fermi...
متن کاملQuantum ripples in strongly correlated metals.
We study how well-known effects of the long-ranged Friedel oscillations are affected by strong electronic correlations. We first show that their range and amplitude are significantly suppressed in strongly renormalized Fermi liquids. We then investigate the interplay of elastic and inelastic scattering in the presence of these oscillations. In the singular case of two-dimensional systems, we sh...

متن کاملAnisotropic Friedel oscillations in graphene-like materials: The Dirac point approximation in wave-number dependent quantities revisited
Friedel oscillations of the graphene-like materials are investigated theoretically for low and intermediate Fermi energies. Numerical calculations have been performed within the random phase approximation. It was demonstrated that for intra-valley transitions the contribution of the different Dirac points in the wave-number dependent quantities is determined by the orientation of the wave-numbe...
متن کاملExact Friedel oscillations in the g = ½ Luttinger liquid
Exact Friedel oscillations in the g = 1 2 Luttinger liquid. Abstract: A single impurity in the 1D Luttinger model creates a local modiication of the charge density analogous to the Friedel oscillations. In this paper, we present an exact solution of the case g = 1 2 (the equivalent of the Toulouse point) at any temperature T and impurity coupling, expressing the charge density in terms of a hyp...
