摘要
从Baeriswyl-Bishop模型出发,导出了严格的MX络合物链的连续哈密顿量,得到一组电子波函数满足的方程。进一步严格地求出这组方程的解析解。在零级近似下,该解回到BB的简单扭折孤子解。
An exact solution to the exact continuum model in linear MX complex chain has been obtained on the basis of the continuum version of the charge density wave limit of the Baeriswyl Bishop model,which reduces to BB′s simple kink solution and midgap state in the zeroth approximation.The method used here can be generalized to other similar systems.
