And by using the quantum inverse scattering method, it has been shown that the monodromy matrix satisfies the quantum Yang-Baxter equation(QYBE) on both a finite interval and an infinite interval. So the integrability of this model is proved.

• 文章由一个推广的Lax pair表述形式出发,导出了推广的多分量费米型量子DNLS模型的哈密顿量; 利用量子反散射方法,找到了由Lax矩阵定义的monodromy矩阵在有限间隔和无限间隔情况下所满足的量子Yang-Baxter方程(QYBE),从而证明了模型的可积性;
