Orbital Angular Momentum

Tunable orbital thermoelectric transport with spin-valley coupling in a monolayer of ferromagnetic transition metal dichalcogenides
The valley transport of electrons can carry not only charge but also spin angular momentum and orbital angular momentum (OAM). However, investigations on thermoelectric transport of OAM manipulated by valley degrees of f…

Multifunctional metasurface coding for visible vortex beam generation, deflection and focusing
Vortex beams, as beams carrying orbital angular momentum (OAM), exhibit unique donut-shaped intensity distributions and helical wavefronts. They are widely applied in fields such as optical communication, nanoparticle ma…
