摘 要：

This talk will focus on fermions bound by kink structures. This subject has been considered several times in the literature. However, in many of these studies, the back reaction of the fermions on the kinks has been neglected or considered only in the static case. We included the back reaction of the fermion on the colliding kink-antikink. The fermion field generates a force, either attractive or repulsive,depending on the distribution of the fermion field on kink and antikink.We have shown that the collision and the consequent resonance windows could be highly affected by the presence of the fermion. In this talk, I will also present one of the most fascinating conclusions of our study,which was that the fermion could also mediate the energy exchange mechanism, generating resonance windows even for integrable sine-Gordon model.
