Optical vortex beams, characterized by their helical phase fronts and orbital angular momentum (OAM), are pivotal in applications such as high-capacity communication, optical manipulation, and quantum ...

The high-energy radiation that carries orbit angular momentum has become an extremely important tool to investigate the angular momentum-related physics in the microworld. But the generation and ...

The frigid stream of air that plunged down into the Central U.S. this week is breaking cold records from South Dakota to Texas, with temperatures in the single digits setting records in many locations ...
