Extended integrability regime for the supersymmetric U model | Jon Links
; | Date: |
18 Mar 1999 | Journal: | J. Phys. A: Math. Gen., 32 (1999) L315 | Subject: | Strongly Correlated Electrons; Exactly Solvable and Integrable Systems | cond-mat.str-el nlin.SI solv-int | Abstract: | An extension of the supersymmetric U model for correlated elctrons is given and integrability is established by demonstrating that the model can be constructed through the Quantum Inverse Scattering Method using an R-matrix without the difference property. Some general symmetry properties of the model are discussed and from the Bethe ansatz solution an expression for the energies is presented. | Source: | arXiv, cond-mat/9903274 | Services: | Forum | Review | PDF | Favorites |
