Abstract: (Elsevier)
We consider the Ferromagnetic-String-Formation-Probability correlation function (FSFP) for the spin - 1 2 Heisenberg XXZ chain. We construct a , completely integrable system of integro-difference equations (IDE), which has the FSFP as a , τ-function. We derive the associated Riemann-Hilbert problem and obtain the long-distance asymptotics of the FSFP correlator in some limiting cases.
