The role of a chiral quantum-dot molecule (QDM) system in controlling and enhancing the
Goos-Hänchen (GH) shift is revealed here. The proposed setup is a four-level atomic system …

We study the interaction of laser pulses carrying orbital angular momentum (OAM) with
structural asymmetry quantum-dot molecules characterized by four energy levels. We …

Enhancing the optical response and Fresnel–Fizeau light dragging in relation to photon plus
surface plasmons through various coupled atomic–metal plasmonic interfaces has prompted …

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 …

We present a novel methodology for enhancing superluminal surface plasmon polaritons
(SPPs) propagations within a hybrid nanostructure configuration consisting of gold (Au) …

Owing to their peculiar properties of great fundamental and practical implications, surface
plasmons and exciton-plasmons interaction have attracted immense interest in the recent …

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 …

Optical properties of surface plasmon polaritons (SPPs) and drag of photon and SPPs
attracted great attention owing to multi-fold potential fundamental and technological …

We theoretically investigate the lateral and rotary light-drag in semiconductor three-level
InAs/GaAs double quantum dot molecules. No coherent laser fields are used and the …

The giant Kerr nonlinearity with reduced linear and nonlinear absorption in a four-level
quantum dot by employing the tunnel coupling is investigated. It is shown that by …
