T−W relation and spectrum of supersymmetric t−J model without U(1) symmetry

We propose a novel characterization of the exact solution of the one-dimensional supersymmetric t−Jmodel with generic non-diagonal boundary conditions. Instead of using Bethe roots, we parameterize the eigenvalues of transfer matrix in the spin sector with their zero-roots. By constructing the t−Wre...

description We propose a novel characterization of the exact solution of the one-dimensional supersymmetric t−Jmodel with generic non-diagonal boundary conditions. Instead of using Bethe roots, we parameterize the eigenvalues of transfer matrix in the spin sector with their zero-roots. By constructing the t−Wrelation, we obtain the explicit forms of the eigenvalues of the system and the homogeneous Bethe ansatz equations. This scheme is universal and can be applied to other quantum integrable systems with or without U(1)symmetry.
