Modulated Kink-Antikink Collisions in System of Coupled Models.

We present a method to modulate two-bounce resonance structure observed in process of kink-antikink collisions in the 1+1 dim model with double-well potential. This is done by coupling of the model to the second scalar sector with radiation propagating over the vacuum. Our results show that the fractal structure in the soliton collisions can be modulated perturbatively and new sequence of two-bounce windows appear as coupling constant increases. An effective model of this mechanism is constructed.

Key words: kink-antikink collisions, coupled model, modulated fractal dynamics
