Abstract: (Elsevier)
Using the algebraic Bethe ansatz method, and the solution of the quantum inverse scattering problem for local spins, we obtain multiple integral representations of the n -point correlation functions of the XXZ Heisenberg spin- 1 2 chain in a constant magnetic field. For zero magnetic field, this result agrees, in both the massless and massive (anti-ferromagnetic) regimes, with the one obtained from the q-deformed KZ equations (massless regime) and the representation theory of the quantum affine algebra U q ( sl ̂ 2 ) together with the corner transfer matrix approach (massive regime).- 75.10.Jm
