Exploring the Frontiers of Light and Matter Interaction

Research Focus of the Quantum Materials and Nanophotonics Laboratory

Theoretical Research

The Quantum Optics and Nanophotonics Research Group has a robust and multifaceted research trajectory spanning across quantum mechanics, photonics, and nanotechnology. The core of the group's research delves into the exploration and understanding of quantum dots, and their diverse configurations and potentials. The group has particularly focused on quantum dots shaped as spherical, ellipsoidal, cylindrical, and conical, among others.

Experimental Research

The experimental arm of our research is dedicated to the pioneering development of quantum dot liquid crystal composites (QDLCs). In this venture, we combine the unique spectral and wavefunction properties of QDs with the high responsiveness of liquid crystals to external stimuli. Our experimental efforts are geared towards harnessing and enhancing the electrooptical, magnetic, and thermal properties of QDLCs. This involves careful consideration of various factors such as the concentration, shape, and material composition of QDs. This experimental direction is integral in translating theoretical predictions into practical, innovative applications within the realm of nanotechnology, marking a significant step forward in the material sciences.
