This work proposes a double quantum dot (DQD) system, with a wetting layer (WL) is
included, to study the negative refractive index (NRI) under the application of the electric …

The control and enhancement of superluminal pulse propagation via a chiral quantum-dots
(QDs) system is presented in this article. The proposed system is a double chiral QDs four …

A model of electromagnetically induced grating (EIG) assisted by the spontaneously
generated coherence (SGC) in the ladder-plus-Y double quantum dot (DQD) system is …

This work proposes a double quantum dot structure as an intermediate-band layer to
developing solar cell performance for the first time. The continuity-current equation is …

This article investigates the effect of the detuning interaction parameters of a single-mode
electromagnetic field with a five-level Λ-type. The differential system is solved in the …

The modulation of exciton energy and state density of layer-structured transition metal
dichalcogenides (TMDs) is required for diverse optoelectronic device applications. Here, the …

The aim of this paper is to study the interaction between a single mode field and four-level
atom in N-configuration under nonlinear medium effect. The non-resonance case and the …

We study the optical properties of a four-level Y system theoretically in^ 87 87 Rb atoms
using density matrix formalism. On account of wavelength mismatching effects in the system …

In this paper, the transient absorption and particle population in a two-field-driven ladder-
type three energy level atomic system is simulated numerically with the density matrix …

Taking advantage of the short pulse duration and the high repetition rate of the fs pulse train,
amplification without inversion (AWI) can be achieved in two-or three-level atomic systems …
