Semiconductors in all dimensionalities ranging from 0D quantum dots and molecules to 3D
bulk crystals support bound electron–hole pair quasiparticles termed excitons. Over the past …

The field of two-dimensional (2D) materials-based nanophotonics has been growing at a
rapid pace, triggered by the ability to design nanophotonic systems with in situ control …

The main aspects of physical phenomena associated with the optical orientation of the spin
and valley degrees of freedom in transition metal dichalcogenide monolayers and in van der …

Excitons in monolayer transition-metal-dichalcogenides (TMDs) dominate their optical
response and exhibit strong light–matter interactions with lifetime-limited emission. While …

We investigate the exciton fine structure in atomically thin WSe 2-based van der Waals
heterostructures where the density of optical modes at the location of the semiconductor …

Metasurfaces enable flat optical elements by leveraging optical resonances in metallic or
dielectric nanoparticles to obtain accurate control over the amplitude and phase of the …

Optical absorption is one of the most fundamental processes in light-matter interactions. The
ability to achieve and control high absorption is crucial for a broad range of modern photonic …

The exciton valley dynamics in van der Waals heterostructures with transition metal
dichalcogenide monolayers is driven by the long-range exchange interaction between the …

The resonance energy and the transition rate of atoms, molecules, and solids were
understood as their intrinsic properties in classical electromagnetism. It was later realized …

We report on the optical preparation of coherent superpositions of exciton and biexciton
states manifested in temporal nonlinear oscillations in interacting exciton gases. The effect is …
