Dynamical correlation functions of the XXZ spin-1/2 chain
N. Kitanine, J. M. Maillet, N. A. Slavnov +1
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,…

Master equation for spin-spin correlation functions of the XXZ chain
N. Kitanine, J. M. Maillet, N. A. Slavnov +1
We derive a new representation for spin-spin correlation functions of the finite XXZ spin-1/2 Heisenberg chain in terms of a single multiple integral, that we call the master equat…
