Resumen de Correlation functions of the XXZ Heisenberg spin chain: Bethe ansatz approach

Jean Michel Maillet

• We review recent progress in the computation of correlation functions of the XXZ spin-1/2 chain. We describe both finite and infinite chain results. Long distance asymptotic behavior is discussed. Our method is based on the resolution of the quantum inverse scattering problem in the framework of the algebraic Bethe ansatz.
