Dynamics of strongly interacting kink-antikink pairs for scalar fields on a line
Dynamics of strongly interacting kink-antikink pairs for scalar fields on a line
This paper concerns classical nonlinear scalar field models on the real line. If the potential is a symmetric double-well, such a model admits static solutions called kinks and antikinks, which are perhaps the simplest examples of topological solitons. We study pure kink-antikink pairs, which are solutions that converge in one …
