“…Figure 2 shows, for photon energy 1.517 eV, the tangential and radial enhancement factors |E x | and |E z | of the electric fields, respectively, as well as the enhancement factor for the decay rate of the quantum emitter [31]. The results presented in figure 2 are in agreement with that presented in references [32][33][34]. We observe that the |E x | factor decreases up to d ≈ 5 nm, but after that point, it starts to increase; however at all d shown here, its value is smaller than one.…”

We investigate theoretically the population transfer process in a Λ-type three-level quantum system near a metallic nanosphere using the Stimulated Raman Adiabatic Passage (STIRAP) technique. We combine density matrix quantum dynamical calculations with first-principle electromagnetic calculations, which quantify the influence of the plasmonic nanoparticle on the electric field of the pump and Stokes pulses in STIRAP as well as on the spontaneous emission rates within the Λ-type system. We study the population transfer process by varying the free-space spontaneous emission rate, the distance of the quantum system from the nanosphere, the polarization direction with respect to the nanoparticle surface and the relative strength of the pump and Stokes pulses used in STIRAP. We find that when the pump and Stokes fields have tangential and radial polarizations with respect to the nanosphere surface, the transfer efficiency is improved due to the increase of the decay rate of the excited state to the target state relatively to the decay to the initial state. The optimal population transfer is achieved for small interparticle distances, moderate free space spontaneous decay rate, large values of the pump Rabi frequency and small values of the Stokes Rabi frequency. When we exchange the polarization directions of the pump and Stokes fields we can still find a range of parameters where the population transfer remains efficient, but larger Stokes Rabi frequencies are necessary to overcome the increased decay rate from the excited state back to the initial state.

“…In [ 131 ], the authors showed that the presence of a plasmonic NP leads as to a strong modification of the resonance fluorescence spectrum, as to transition from antibunching to bunching for fluorescent photons. In [ 144 ], the same authors investigated the statistics of the emission of a two-level QE near the same two-dimensional array of dielectric nanospheres with a metal coating. It was shown that the photon statistics is significantly modified by a lattice of NPs.…”

This review is devoted to the study of effects of quantum optics in nanostructures. The mechanisms by which the rates of radiative and nonradiative decay are modified are considered in the model of a two-level quantum emitter (QE) near a plasmonic nanoparticle (NP). The distributions of the intensity and polarization of the near field around an NP are analyzed, which substantially depend on the polarization of the external field and parameters of plasmon resonances of the NP. The effects of quantum optics in the system NP + QE plus external laser field are analyzed—modification of the resonance fluorescence spectrum of a QE in the near field, bunching/antibunching phenomena, quantum statistics of photons in the spectrum, formation of squeezed states of light, and quantum entangled states in these systems.

“…However, there is another widely used methodology for studying light-matter interaction in quantum systems near plasmonic nanostrucrures which is based on the electromagnetic Green's tensor, see, e.g., Refs. [63][64][65][66][67][68] , which uses linear density matrix equations, as the Green's tensor does not lead to a direct nonlinearity in the density matrix equations. One may induce indirectly a nonlinearity in the linear density matrix equations of the electromagnetic Green's tensor approach when a self-consistent scheme is considered and the local field correction to the electric field interacting with the quantum system is introduced, as it was shown by Hayati et al 69 .…”

We study the potential for controlled transfer of population to the biexciton state of a semiconductor quantum dot coupled with a metal nanoparticle, under the influence of an electromagnetic pulse with hyperbolic secant shape, and derive analytical solutions of the density matrix equations, for both zero and nonzero biexciton energy shift. These solutions lead to efficient transfer to the biexciton state, for various interparticle distances, including relatively small values. In certain cases, when the distance between the two particles is small, the transfer of population is strongly modified because of the influence of surface plasmons to the excitons, and the effect is more pronounced for shorter pulses. The hybrid snanostructure that we study has been proposed for generating efficiently polarization-entangled photons, thus the successful biexciton state preparation considered here is expected to contribute in this line of research.
