Generating function for sine-Gordon correlators in finite volume from
the inhomogeneous XXZ chain [PDF]
Francesco BuccheriWe present an expression for the generating function of correlation functions in the sine-Gordon integrable field theory with finite space direction, deriving it from the Destri-De Vega integrable lattice regularization formulated as an inhomogeneous Heisenberg XXZ spin chain and from more recent advances in the computations of spin form factors in the thermodynamic limit.View original: http://arxiv.org/abs/1206.1528
