Completeness of the SO(4) extended Bethe Ansatz for the One-dimensional Hubbard Model

چکیده
We show how to construct a complete set of eigenstates of the hamiltonian of the one-dimensional Hubbard model on a lattice of even length L. This is done by using the nested Bethe Ansatz and the SO(4) symmetry of the model. We discuss in detail how the counting of independent eigenstates is carried out.

Integrable variant of the one-dimensional Hubbard model
Abstract. A new integrable model which is a variant of the one-dimensional Hubbard model is proposed. The integrability of the model is verified by presenting the associated quantum R-matrix which satisfies the Yang-Baxter equation. We argue that the new model possesses the SO(4) algebra symmetry, which contains a representation of the η-pairing SU(2) algebra and a spin SU(2) algebra. Additiona...
متن کاملAlgebraic Bethe ansatz approach for the one - dimensional Hubbard model
We formulate in terms of the quantum inverse scattering method the algebraic Bethe ansatz solution of the one-dimensional Hubbard model. The method developed is based on a new set of commutation relations which encodes a hidden symmetry of 6-vertex type.
متن کاملThe half - filled Hubbard chain in the Composite Operator Method : A comparison with Bethe Ansatz
– The one-dimensional Hubbard model at half-filling is studied in the framework of the Composite Operator Method using a static approximation. A solution characterized by strong antiferromagnetic correlations and a gap for any nonzero on-site interaction U is found. The corresponding ground-state energy, double occupancy and specific heat are in excellent agreement with those obtained within th...
متن کاملBethe-ansatz studies of energy level crossings in the one-dimensional Hubbard model
Motivated by Heilmann and Lieb’s work [8], we discuss energy level crossings for the one-dimensional Hubbard model through the Bethe ansatz, constructing explicitly the degenerate eigenstates at the crossing points. After showing the existence of solutions for the Lieb–Wu equations with one-down spin, we solve them numerically and construct Bethe ansatz eigenstates. We thus verify all the level...
متن کاملThe Analytic Bethe Ansatz for a Chain with Centrally Extended su(2|2) Symmetry
We investigate the integrable structure of spin chain models with centrally extended su(2|2) and psu(2, 2|4) symmetry. These chains have their origin in the planar AdS/CFT correspondence, but they also contain the one-dimensional Hubbard model as a special case. We begin with an overview of the representation theory of centrally extended su(2|2). These results are applied in the construction an...
