Quasinormal modes in kink excitations and kink–antikink interactions: a toy model

Abstract We study excitations and collisions of kinks in a scalar field theory where the potential has two minima with $$Z_2$$ Z2 symmetry. The field potential is designed to create a square well potential in the stability equation of the kink excitations. The stability equation is analogous to the...
