Field theory approach to one-dimensional electronic systems

Abstract

In this talk I describe a recently introduced field-theoretical approach that can be used as an alternative framework to study one-dimensional systems of highly correlated particles.Comment: 25 pages, latex, no figures. Talk delivered at Trends in Theoretical Physics - CERN - Santiago de Compostela - La Plata Meeting, La Plata, April-May 1997, to be published. Abstract modifie
