Non-linear integral equations for the XXX spin-1/2 quantum chain with non-diagonal boundary fields
Holger Frahm, Andreas Klümper, Dennis Wagner +1
The XXX spin- Heisenberg chain with non-diagonal boundary fields represents a cornerstone model in the study of integrable systems with open boundaries. Despite its si…

Integro-Difference Equation for a correlation function of the spin- Heisenberg XXZ chain
F. H. L. Essler, H. Frahm, A. R. Its +1
We consider the Ferromagnetic-String-Formation-Probability correlation function (FSFP) for the spin- Heisenberg XXZ chain. We construct a completely integrable system of…
