Generating function for sine-Gordon correlators in finite volume from the inhomogeneous XXZ chain
Francesco Buccheri
We present an expression for the generating function of correlation functions of the sine-Gordon integrable field theory on a cylinder, with compact space. This is derived from the…

The integrable O(6) model and the correspondence: checks and predictions
Francesco Buccheri, Davide Fioravanti
We exactly compute the energy density of the integrable O(n) non-linear sigma model as a convergent series. This series is specifically analysed for the very important O(6) symmetr…
