Zero-sound solitons in an interacting electron gas in one dimension

Research output: Contribution to journalArticlepeer-review

Abstract

It is shown that the semiclassical approximation may apply to the interacting electron gas in one dimension, in which case the zero-sound oscillations may give rise to classical solitons. They appear as kink solutions of the backward-scattering and the umklapp-scattering sine-Gordon equation.
