Single excitation migration in molecular chain with an attached molecular structure: non-adiabatic polaron model

In this paper we consider the possibility of the stable migration of the single vibron excitation in the system consisting of biomolecule and the attached molecular structure. The model is based on the assumption of the vibron self-trapping and the formation of the non-adiabatic polaron quasiparticle. We have shown that, contrary to the prediction of the non-polaron model, the excitation appears on a large intramolecular distance from its origin with a high probability.
