The generation, manipulation, storage, and detection of single photons play a central role in
emerging photonic quantum information technology. Individual photons serve as flying …

Exciton science sits at the intersection of chemical, optical and spin-based implementations
of information processing, but using excitons to conduct logical operations remains relatively …

Typically, bright excitons (XB) emit light in two-dimensional (2D) layered hybrid perovskites.
There are also dark excitons (XD), for which radiative recombination is spin-forbidden …

A double-edged sword in two-dimensional material science and technology is optically
forbidden dark exciton. On the one hand, it is fascinating for condensed matter physics …

We present a design study of quantum light sources based on hybrid circular Bragg gratings
(CBGs) for emission wavelengths in the telecom O-band. The evaluated CBG designs show …

Photochemical reactions are among the most important reactions in both theoretical studies
and practical applications, since they utilize photon energy as the primary driving force. The …

Dark exciton states show great potential in condensed matter physics and optoelectronics
because of their long lifetime and rich distribution in band structures. Therefore, they can …

Gallium telluride (GaTe) is a two-dimensional (2D) semiconductor that has received
considerable attention due to its potential applications in solid state optics and electronics …

When a detuned and strong laser pulse acts on an optical transition, a Stark shift of the
corresponding energies occurs. We analyze how this optical Stark effect can be used to …

The coupling between excitons in semiconductors or molecules and metal nanoparticles
has been well-studied, primarily for nanoparticles in their ground electronic state. However …
