We investigate theoretically the effects of interaction between an opticaldipole (semiconductor quantum dot or molecule) and metal nanoparticles. Thecalculated absorption spectra of hybrid structures demonstrate strong effectsof interference coming from the exciton-plasmon coupling. In particular, theabsorption spectra acquire characteristic asymmetric lineshapes and stronganti-resonances. We present here an exact solution of the problem beyond thedipole approximation and find that the multipole treatment of the interactionis crucial for the understanding of strongly-interacting exciton-plasmonnano-systems. Interestingly, the visibility of the exciton resonance becomesgreatly enhanced for small inter-particle distances due to the interferencephenomenon, multipole effects, and electromagnetic enhancement. We find thatthe destructive interference is particularly strong. Using our exact theory, weshow that the interference effects can be observed experimentally even in theexciting systems at room temperature.
