Реферат: | eng: The effect of local fields of induced dipoles in metal nanoparticles located in the vicinity of long molecular chains of J-aggregates of dyes on the formation of exciton excitations is investigated. Exciton dynamics equations taking into account the change in dipoles of monomers under the action of local excitation of a molecule by external dc and ac fields are derived. It is shown that a local bistable dependence of the excitation amplitude of the external AC field is observed in the vicinity of a nanoparticle. Numerical analysis of the equations reveals that for some field directions, initial positions, and velocities, exciton excitations are localized in the vicinity of nanoparticles. The application of such a nanosystem is considered.
