q-deformed Supersymmetric t-J Model with a Boundary
Bo-Yu Hou, Wen-Li Yang, Yao-Zhong Zhang, Yi Zhen
Abstract
The q-deformed supersymmetric t-J model on a semi-infinite lattice is diagonalized by using the level-one vertex operators of the quantum affine superalgebra Uq[sl(2|1)]. We give the bosonization of the boundary states. We give an integral expression of the correlation functions of the boundary model, and derive the difference equations which they satisfy.
