Ooi, Kai Tan] The effects of plasmonic metallic nanoparticle (MP) and laser control of the optical properties of a quantum system (QS) under electromagnetic induced transparency (EIT) are studied. We provide a general and exact vectorial description for the local fields that depends nonlinearly on the quantum coherences of the QS, leading to a double quantum coherence. The dielectric function of the QS is computed from the density matrix equations for any interparticle distance, probe laser direction/polarization, and phase and dipole orientation. We study the variations of the dielectric function with the laser parameters in the presence of surface plasmon resonance (SPR) in the MP. We found energy level shifts and enhanced long-range Forster interaction due to the SPR and quenching of EIT spectrum at certain QS-MP spacing. The laser control of quantum coherence with plasmonic effects provides new ways for manipulating optical properties and quantum mechanisms in nanomaterials.
