摘要

我们在量子反向散射方法的框架内构建了一个可积分的一维扩展哈伯德模型。在嵌套代数贝特安萨特方法的帮助下，特征值哈密顿问题由一组贝特安萨特方程求解，这些方程的解理应给出正确的能谱。

Bethe ansatz solutions of the 1D extended Hubbard-model

We construct an integrable 1D extended Hubbard model within the framework of the quantum inverse scattering method. With the help of the nested algebraic Bethe ansatz method, the eigenvalue Hamiltonian problem is solved by a set of Bethe ansatz equations, whose solutions are supposed to give the correct energy spectrum.
