Краткое описание

The paper considers the influence of an electrostatic field on the self-localized state dynamics of quasiparticles in a one-dimensional molecular chain. It was shown that a weak electrostatic field accelerates the propagation of the quasiparticle along the chain, which can explain the charge transport processes in molecular systems. The dependence of quasiparticle velocity and its lifetime on field magnitude and the other system parameters was analyzed. As demonstrated below, a resting quasiparticle, belonging to a ring chain, having accumulated some sufficient portion of energy, starts moving in a however weak but non-zero electric field.
