Two-dimensional (2D) transition metal chalcogenides (TMDs) are regarded as promising
materials for micro-optoelectronic devices and next-generation logic devices due to their …

Strong coupling between electronic excitations in materials and photon modes results in the
formation of polaritons, which display larger nonlinearities than their photonic counterparts …

A light beam can be spatially structured in the complex amplitude to possess orbital angular
momentum (OAM), which introduces an extra degree of freedom alongside the intrinsic spin …

Monolayer transition metal dichalcogenides host tightly bound excitons, which dominate
their optoelectronic response even at room temperatures. Light beams are often used to …

Spin–valley coupling in monolayer transition-metal dichalcogenides gives rise to valley
polarization and coherence effect, limited by intervalley scattering caused by exciton …

Photoexcitation of planar Wannier excitons by twisted photons in thin semiconductor films is
investigated. The excitons are assumed to be already created. The explicit general formulas …

The theory of surface photoelectric effect by twisted photons is developed. The explicit
expression for the probability to record a twisted photoelectron is derived. The conditions …

When optical transitions in materials couple strongly to photon modes, light and matter
degrees of freedom can no longer be treated separately with the light-matter coupling taken …
