Opening the door to more efficient orbitronic devices
Electrons have three intrinsic properties: spin, charge and orbital angular momentum. Researchers have long studied how to ...
Light can carry angular momentum in two distinct ways. One comes from polarization, which describes how the electric field ...
Researchers generated stable vortex light in its lowest-energy state using liquid crystal traps and optical confinement.
A South Korean research team has successfully captured the first-ever observation of a 'wind' that explains the birth process ...
Optical vortices—light beams carrying orbital angular momentum (OAM)—are characterized by helical wavefronts and phase ...
Manipulation of structured electromagnetic (EM) waves is key to boosting wireless communications capacity. Recently, scientists have invented a space-time-coding metasurface that generates structured ...
Advancing the rapidly growing field of photonic quantum information processing requires novel, highly scalable methods to ...
