Abstract

For the first time, we used the DFT technology to detect the collision process of single soliton and soliton molecules. Our work reveals the complete dynamic process of elastic collision of single soliton and soliton molecule, especially the soliton molecule disintegrating and the reform of soliton molecule. Numerical simulation shows that gain dynamics is the main physical origin of collision. Our investigations illustrate the particle nature of soliton and supplements the previous research of soliton collision dynamics.
