2 00 3 A note on the Bethe ansatz solution of the supersymmetric t - J model

چکیده
The three different sets of Bethe ansatz equations describing the Bethe ansatz solution of the supersymmetric t-J model are known to be equivalent. Here we give a new, simplified proof of this fact which relies on the properties of certain polynomials. We also show that the corresponding transfer matrix eigenvalues agree.

Algebraic 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...
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 کاملThe Supersymmetric T-j Model with Quantum Group Invariance
An integrable quantum group deformation of the supersymmetric t-J model is introduced. Open boundary conditions lead to an spl q (2; 1) invariant hamiltonian. A general procedure to obtain such invariant models is proposed. To solve the model a generalized nested algebraic Bethe ansatz is constructed and the Bethe ansatz equations are obtained. The quantum supergroup structure of the model is i...
متن کاملThermodynamic Bethe ansatz equation for osp(1|2) integrable spin chain
The thermodynamic Bethe ansatz is applied to a quantum integrable spin chain associated with the Lie superalgebra osp(1|2). Using the string hypothesis, we derive a set of infinite number of non-linear integral equations (thermodynamic Bethe ansatz equation), which characterize the free energy. The low temperature limit of the free energy is also discussed. Modern Physics Letters A, in press. S...
متن کاملCompleteness of the Bethe states for the supersymmetric t-J model.
A complete set of eigenstates for the supersymmetric t-J model in one dimension is obtained by combining the Bethe-ansatz with the Spl(2,1) supersymmetry of the model.
