The Ground State Energy of Small Polaron Gas

Abstract

The ground state energy of the small polaron model is calculated as a function of the electronic density. The applicability of the small polaron model to metals of the TTF-TCNQ family is discussed.On calcule 1'8nergie de l'8tat fondamental du modde de petit polaron en fonction de la densit8 6lectronique. La validit-6 d'qplication du modble de petit polaron aux m8taux de la famille de TTF-TCNQ eat discut8e.
