Drinfeld Twists and Algebraic Bethe Ansatz of the Supersymmetric t-J Model
نویسندگان
چکیده
We construct the Drinfeld twists (factorizing F -matrices) for the supersymmetric t-J model. Working in the basis provided by the F -matrix (i.e. the so-called F -basis), we obtain completely symmetric representations of the monodromy matrix and the pseudo-particle creation operators of the model. These enable us to resolve the hierarchy of the nested Bethe vectors for the gl(2|1) invariant t-J model.

Drinfeld twists and algebraic Bethe ansatz of the supersymmetric model associated with U q ( gl ( m | n ) )
We construct the Drinfeld twists (or factorizing F -matrices) of the supersymmetric model associated with quantum superalgebra Uq(gl(m|n)), and obtain the completely symmetric representations of the creation operators of the model in the F -basis provided by the F -matrix. As an application of our general results, we present the explicit expressions of the Bethe vectors in F -basis for the Uq(g...
متن کاملDrinfeld Twists and Symmetric Bethe Vectors of Supersymmetric Fermion Models
We construct the Drinfeld twists (factorizing F -matrices) of the gl(m|n)invariant fermion model. Completely symmetric representation of the pseudoparticle creation operators of the model are obtained in the basis provided by the F -matrix (the F -basis). We resolve the hierarchy of the nested Bethe vectors in the F -basis for the gl(m|n) supersymmetric model.
متن کاملAlgebraic Bethe ansatz for the gl(1|2) generalized model and Lieb-Wu equations
We solve the gl(1|2) generalized model by means of the algebraic Bethe ansatz. The resulting eigenvalue of the transfer matrix and the Bethe ansatz equations depend on three complex functions, called the parameters of the generalized model. Specifying the parameters appropriately, we obtain the Bethe ansatz equations of the supersymmetric t-J model, the Hubbard model, or of Yang’s model of elec...
متن کاملAlgebraic Properties of the Bethe Ansatz for an Spl(2,1)-supersymmetric T-j Model
We investigate the algebraic structure of the supersymmetric t-J model in one dimension. We prove that the Bethe ansatz states are highest weight vectors of an spl(2,1) superalgebra. By acting with shift operators we construct a complete set of states for this model. In addition we analyse the multiplet structure of the anti-ferromagnetic ground state and some low lying excitations. It turns ou...
متن کاملAlgebraic Bethe ansatz for the gl(1|2) generalized model II: the three gradings
The algebraic Bethe ansatz can be performed rather abstractly for whole classes of models sharing the same R-matrix, the only prerequisite being the existence of an appropriate pseudo vacuum state. Here we perform the algebraic Bethe ansatz for all models with 9×9, rational, gl(1|2)-invariant R-matrix and all three possibilities of choosing the grading. Our Bethe ansatz solution applies, for in...
