Description
We study excitations of solitary waves - the kinks - in scalar models with
degree eight polynomial self-interaction in $(1+1)$ dimensions. We perform
numerical studies of scattering of two kinks with an exponential asymptotic
off each other and analyse the occurring resonance phenomena. We connect these
phenomena to the energy exchange between the translational and the vibrational
modes of the colliding kinks. We also consider the interaction of two kinks
with power-law asymptotic; the latter leads to a long-range interaction
between the two kinks.
