Optical Properties of Nanostructures

Abstract

We analyzed linear molecular chain with exciton excitations for the case when number of excitons is not conserved. The results obtained are in some sense amazing. The dispersion law of finite chain is surface depending on two independent angles. The same conclusion is valid for concentrations of exitons and exciton pairs. As it was expectable physical characteristics of the finite chain depend on spatial coordinates. All results are compared to corresponding results of infinite chain.
