Friedel oscillations in Luttinger liquids
Reinhold Egger, Hermann Grabert
We study the density disturbance of a correlated 1D electron liquid in the presence of a scatterer or a barrier. The 2k_F-periodic density profile away from the barrier (Friedel os…

Low-temperature transport of correlated electrons
R. Egger, M. Sassetti, U. Weiss
Transport properties of a single-channel Luttinger liquid impinging on a barrier have been studied for , where is the dimensionless interaction constant and $|ε| \ll…
