Dynamical correlation functions of the XXZ spin- 1/2 chain
Abstract
We derive a master equation for the dynamical spin-spin correlation functions of the XXZ spin- 1/2 > Heisenberg finite chain in an external magnetic field. In the thermodynamic limit, we obtain their multiple integral representation.
