Application of Nonlinear Lie Algebraic Method to One-Dimensional Spin-2/1 Heisenberg Ferromagnetic Chain

摘要

In our work the nonlinear Lie algebra and concept of shift operator are introduced, based on that the eigenproblem of one-dimensional spin-2/1 Heisenberg ferromagnetic chain can be solved. The results achieved from the ususl Bethe ansatz method are recovered naturally.
