Scattering between wobbling kinks

In this paper the scattering between a wobbling kink and a wobbling antikink in the standard phi(4) model is numerically investigated. The dependence of the final velocities, wobbling amplitudes and frequencies of the scattered kinks on the collision velocity and on the initial wobbling amplitude is discussed. The fractal structure becomes more intricate due to the emergence of new resonance windows and the splitting of those arising in the nonexcited kink scattering. Outside this phase the final wobbling amplitude exhibits a linear dependence of the collision velocity, which is almost independent of the initial wobbling amplitude.

In this paper, numerical investigations were conducted on the scattering between a wobbling kink and a wobbling antikink in the standard phi(4) model. The study discussed the dependence of final velocities, wobbling amplitudes, and frequencies of the scattered kinks on collision velocity and initial wobbling amplitude. The fractal structure becomes more intricate with the emergence of new resonance windows and the splitting of those arising in non-excited kink scattering. Outside this phase, the final wobbling amplitude shows a linear dependence on collision velocity, which is almost independent of the initial wobbling amplitude.
