摘要：

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 tau-function. We derive the associated Riemann-Hilbert problem and obtain the long-distance asymptotics of the FSFP correlator in some limiting cases.
