Interactions of adjacent pulsating, erupting and creeping solitons

This paper investigates the adjacent interactions of three novel solitons for thequintic complex Ginzburg--Landau equation, which are plain pulsating,erupting and creeping solitons. It is found that differentperformances are presented for different solitons due to isolated regions ofthe parameter space where they exist. For example, plain pulsating anderupting solitons exhibit mutual annihilation during collisions with thedecrease of total energy, but for creeping soliton, the two adjacentpulses present soliton fusion without any loss of energy. Otherwise, themethod for restraining the interactions is also found and it can suppressinteractions between these two adjacent pulses effectively.
