On scalar products and form factors by Separation of Variables: the antiperiodic XXZ model
H. Pei, V. Terras
We consider the XXZ spin-1/2 Heisenberg chain with antiperiodic boundary conditions. The inhomogeneous version of this model can be solved by Separation of Variables (SoV), and the…

Correlation functions by Separation of Variables: the XXX spin chain
G. Niccoli, H. Pei, V. Terras
We explain how to compute correlation functions at zero temperature within the framework of the quantum version of the Separation of Variables (SoV) in the case of a simple model:…
