一维N能级原子链中的孤波

SOLITARY WAVES IN AN ONE DIMENSIONAL CHAIN OF N LEVEL ATOMS

本文利用实指数方法研究ＤＮＬＳ方程的孤波解，结果发现ＤＮＬＳ方程除了标准的孤子解外。

Real exponential method is used to study the solitary wave solutions of the dark discrete nonlinear Schrodinger (DNLS) equation and the results show that the dark DNLS equation has many new solitary wave solutions except the standard one.
