Abelian Bosonization, the Wess-Zumino Functional and Conformal Symmetry

TL;DR

This paper explores the equivalence between the massive Thirring and sine-Gordon models, revealing an underlying conformal symmetry beyond perturbative mass calculations.

Contribution

It uncovers a conformal symmetry in the equivalence of the models, extending previous perturbative results to a more fundamental level.

Findings

Established a non-perturbative link between the models

Uncovered underlying conformal symmetry

Extended understanding of bosonization techniques

Abstract

We look at the equivalence of the massive Thirring and sine-Gordon models. Previously, this equivalence was derived perturbatively in mass (though to all orders). Our calculation goes beyond that and uncovers an underlying conformal symmetry.
