We propose a mechanism of intravalley spin-flip scattering in spin-valley coupled two dimensional systems by transferring momentum of light into exciton center of mass using optical vortex (OV) beams. By varying the dispersion of light using the topo

Spin-valley coupling in monolayer transition metal dichalcogenides gives rise to valley polarization and coherence effect, limited by intervalley scattering caused by exciton-phonon, exciton-impurity, and electron-hole exchange interaction (EHEI). We

Linearly polarized excitons in anisotropic semiconductors like ReS2 pose intriguing possibilities in photonics and condensed matter physics. Here, we stack multilayer ReS2 on a dielectric mirror, creating anisotropic exciton-polaritons which show tun
