Integrability of the Heisenberg Chains with Boundary Impurities and Their Bethe Ansatz
Boyu Hou, Kangjie Shi, Ruihong Yue +1
In this paper, we show the integrability of spin-1/2 XXZ Heisenberg chain with two arbitrary spin boundary Impurities. By using the fusion method, we generalize it to the spin-1 XX…
Bethe Ansatz for the Spin-1 XXX Chain with Two Impurities
Boyu Hou, Kangjie Shi, Ruihong Yue +1
By using algebraic Bethe ansatz method, we give the Hamitonian of the spin-1 XXX chain associated with with two boundary impurities.
The Exact Solution of the SU(3) Hubbard Model
Buoyu Hou, Dantao Peng, Ruihong Yue
The Bethe ansatz equations of the 1-D SU(3) Hubbard model are systematically derived by diagonalizing the inhomogeneous transfer matrix of the XXX model. We first derive the scatte…
Vertex Operators of and Highest Weight Representations of
Wen-Li Yang, Yao-Zhong Zhang
We determine the exchange relations of the level-one q-vertex operators of the quantum affine superalgebra . We study in details the level-one irreducible highe…
Level-One Highest Weight Representations of and Associated Vertex Operators
Wen-Li Yang, Yao-Zhong Zhang
We study the level-one irreducible highest weight representations of and associated q-vertex operators. We obtain the exchange relations satisfied by the verte…
Boundary Kondo impurities in the generalized supersymmetric t-J model
Heng Fan, Miki Wadati, Rui-hong Yue
We study the generalized supersymmetric t-J model with Kondo impurities in the boundaries. We first construct the higher spin operator K-matrix for the XXZ Heisenberg chain. Settin…
