RPAE versus RPA for the Tomonaga model with quadratic energy dispersion
K. Schönhammer
Recently the damping of the collective charge (and spin) modes of interacting fermions in one spatial dimension was studied. It results from the nonlinear correction to the energy…

Luttinger Liquids: The Basic Concepts
K. Schonhammer
This chapter reviews the theoretical description of interacting fermions in one dimension. The Luttinger liquid concept is elucidated using the Tomonaga-Luttinger model as well as…
