Due to the limited study, this work engineers the parameters controlling the rate of absorbed energy from a double quantum dot (DQD)-metal nanoparticle (MNP) system at plasmonic electromagnetically induced transparency (PEIT) considering the strong coupling between DQD and MNP. The modeling is of the material property for which the energy states and transition momenta are calculated. The analysis considers the orthogonalized plane wave between the wetting layer (WL)-QD transitions. A huge ð10 −5 WÞ total absorption rate ðQ total Þ from the system is attained. This result is higher by four orders and the power applied is less by three orders than that obtained in the literature. Many features are studied. Neglecting the WL, the system spectrum is similar to the left-handed picture of the system with WL. The value of Q depends on the situation of the QD energy states through the variation of the QD size, MNP radius, and distance separating the system. In the DQD-MNP hybrid system, the controlling factor that gives a high Q total in the PEIT case is the DQD combination with a weak probe and enough pump, i.e., the DQD structure works as a whole structure, not as two QDs working separately. Such a structure allows for manipulating the flexibility of carriers between DQD states that are not found in other structures. From the results, one can conclude that DQD behavior under the pump, probe, and single tunneling component produces two transparent windows. Adding a second tunneling component creates four transparency windows depending on the values of these applied parameters.

Splitting of the effective Rabi frequencies for plasmonic fields when the interaction occurs between semiconductor quantum dot and three metallic nanospheres in the presence of three electromagnetic fields is examined. We study theoretically the role of the dipole–dipole interactions in creating many Multipoles. Then, we split the effective Rabi frequencies into three parts according to the quantitative Multipoles of the plasmonic fields. The density matrix equations are derived for the description of the optical properties of the SQD-MNPs nanosystem. We investigate the influence of each part of the effective Rabi frequencies and compare them with each other individually. The three parts of the effective Rabi frequency for the probe field are affected by changing the angles, the strong probe field and other parameters for the hybrid system.
