Massless Sine-Gordon and Massive Thirring Models: proof of the Coleman's equivalence

arXiv:0711.5010 · doi:10.1007/s00220-008-0619-x

Abstract

We prove the Coleman's conjecture on the equivalence between the massless Sine-Gordon model with finite volume interaction and the Thirring model with a finite volume mass term.
