On integrable Hamiltonians for higher spin XXZ chain | | Andrei G. Bytsko
; | | Date: |
18 Dec 2001 | | Journal: | J.Math.Phys. 44 (2003) 3698-3717 | | Subject: | High Energy Physics - Theory; Exactly Solvable and Integrable Systems; Strongly Correlated Electrons | hep-th cond-mat.str-el nlin.SI | | Abstract: | Integrable Hamiltonians for higher spin periodic XXZ chains are constructed in terms of the spin generators; explicit examples for spins up to 3/2 are given. Relations between Hamiltonians for some U_q(sl_2)-symmetric and U(1)-symmetric universal r-matrices are studied; their properties are investigated. A certain modification of the higher spin periodic chain Hamiltonian is shown to be an integrable U_q(sl_2)-symmetric Hamiltonian for an open chain. | | Source: | arXiv, hep-th/0112163 | | Services: | Forum | Review | PDF | Favorites | |
