A new algebraic Bethe ansatz for gl(2, 1) invariant vertex models

authored by: M. P. Pfannmuller, H. Frahm
Abstract: The algebraic Bethe ansatz for the integrable vertex model constructed from the four-dimensional [b, 1/2] representation of the superalgebra gl(2, 1) is calculated using a ferromagnetic reference state. This Bethe ansatz was known only for the three-dimensional [1/2]₊ representation leading to the supersymmetric t-J model. The necessary modification of the nested algebraic Bethe ansatz scheme and generalizations to related models are discussed.
