Abstract

The standard description of (three-dimensional) metals is based on the Landau theory of Fermi systems (Fermi Liquid theory) [1]. Within this theory all low-energy and low- temperature properties are described in terms of independent elementary excitations (quasi- particles) which behave more or less as free particles. This picture breaks down in one dimensional systems, which are instead described by the so called Luttinger Liquid theory [2]. Indeed experimental evidence suggests that Fermi Liquid theory could break down in a variety of physical situations.
