Abstract
We investigate kink-antikink scattering in the model in the presence of an additional scalar field, , that is in its quantum vacuum and interacts with via a term where is the coupling. The final state of such a scattering is either a bound state with eventual annihilation or a reflection of the kink-antikink pair. Without the field, the outcome is known to depend fractally on the initial velocity of the kink-antikink pair. In the quantum vacuum of the field, the fractal dependence gets modified and disappears above a critical interaction strength, .
