Complete Pseudoparticle Operator Representation for Integrable Electronic Luttinger Liquids

Abstract

We introduce the pseudoparticle operator algebra that generates all Hubbardchain eigenstates from a single reference vacuum. The occurence of only zeromomentum pseudoparticle forward scattering at all energy scales combined with the infinite pseudoparticle-number conservation laws establish this operator basis as the most suitable for dealing with transport properties at finite frequencies. We discuss the explicit form of the finite-frequency conductivity in these models
