Kink Collision in the Noncanonical Φ⁶ Model: A Model with Localized Inner Structures

Multikink scattering in the $ϕ^6$ model revisited

“…Let us now focus on the moduli space metric resulting from the restricted set of configurations (26). The main observation is that, contrary to the kink-antikink collision in φ 4 theory, the relativistic moduli space metric has no singularity for any finite a as there is no null vector issue.…”

“…Although the recent progress in the explanation of the K K collisions in the φ 4 model [19,20] is a significant step forward in the understanding of the dynamics of solitons, it is just a beginning. There are many kink models whose dynamics are still understood to a rather unsatisfactory extent, see, e.g., deformations of the φ 6 model [24][25][26], higher order potentials [28][29][30][31], double sine-Gordon [32][33][34][35] and other models [36][37][38][39][40][41][42].…”
