Analyses reveal oscillatory forces and bound states between kink and antikink solitons in a biharmonic model, indicating new equilibria.

This research aims to explore the interaction forces between kink and antikink solitons in a biharmonic model.
Calculated the force between widely separated kink and antikink solitons.
Utilized ordinary differential equations to determine their motion.
Compared asymptotic analysis with numerical computations.
Identified properties of the interaction such as exponentially-decaying oscillatory behavior.
Observed that the interaction force exhibits an oscillatory behavior unlike the monotonically attractive behavior in the Klein–Gordon theory.
Predicted an infinite set of field theory equilibria or kink–antikink bound states.
Confirmed several bound states and evaluated their stability via partial differential equations.

Decker et al. (2020) studied this question.
