We study simultaneous collisions of two, three, and four kinks and antikinks of the Phi6 model at the same spatial point. Unlike the Phi4 kinks, the Phi6 kinks are asymmetric and this enriches the variety of the collision ...

Creation of solitons as kink–antikink pairs from particles is investigated, in the Phi4 model. Particle-like states are simulated by two widely separated identical wave trains which are propagated toward collision point ...

Recently for the sine-Gordon equation it has been established that during collisions of N slow kinks maximal energy density increases as N 2 . In this numerical study, the same scaling rule is established for the non-integrable ...
