一维小极化子模型的代数Bethe-Ansatz方程

ALGEBRAIC BETHE-ANSATZ EQUATIONS FOR A SMALL-POLARON MODEL

本文由一个特殊非对称六顶角模型的L矩阵出发,构造了一维小极化子模型的代数Bethe-Ansatz方程.结果表明,由该方程所得的能谱与用坐标Bethe-Ansatz方法所得的结果一致.

Algebraic Bethe-Ansatz equations for a small-polaron modal are constucted from the L- matrix for a special asymmetric six-vertex medel. The results show that the energy spectrum obtained coincides with that derived from the coordinate Bethe- Ansatz technique.
