Despite the complexity, the exact link between these super-regular breathers and MI is established strictly. （3）Chong Liu, Zhan-Ying Yang, Wen-Li Yang, and Nail Akhmediev, Chess-Board-Like Spatio-Temporal Interference Patterns and Their Excitation, arXiv:1810.03232v1. New type of interference pattens has been obtained, which can be observed in many nonlinear systems.
