In magnetic systems, interactions between electrons can be described by an effective spinspin interaction. When the wavefunctions of the electrons overlap mainly in one direction, the system behaves as an effectively one-dimensional spin chain. A special class of such a spin chain is the anisotropic Heisenberg model, also called the XXZ model. Exact wavefunctions for the (gapped) antiferromagnetic XXZ model are obtained using the (algebraic) Bethe Ansatz. A new result is a classification of two… CONTINUE READING
