Abstract

We present a self-consistent approach based on Green’s function formalism allowing us to calculate local electromagnetic properties of a complex system consisting of a single-electron spherical quantum dot (QD) interacting with a dielectric mesoparticle. The cases of static and frequency dependent dielectric permittivity of the mesoparticle were considered. In the static case, due to the coupling between the QD and the mesoparticle, the absorption spectrum of the QD gets redshifted. In the frequency dependent case, the absorption line splits into two peaks. The strongest splitting was observed when the resonance frequency of the mesoparticle is close to the transition frequency of the QD. The interaction effects depend on the polarization of the incident light and diminish with increasing of the interparticle distance.
