Friedel oscillations in the open Hubbard chain

Friedel oscillations in relativistic nuclear matter.

We calculate the low-momentum N-N effective potential obtained in the OBE approximation, inside a nuclear plasma at finite temperature, as described by the relativistic σ-ω model. We analyze the screening effects on the attractive part of the potential in the intermediate range as density or temperature increase. In the long range the potential shows Friedel-like oscillations instead of the usu...

Exact 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...
