A research team led by Associate Prof. Wang Anting from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS) proposed a method for multidimensional ...

This calculated diffraction image shows how forked diffraction gratings shape the atoms' wave function into a vortex. (Courtesy: Science/AAAS) A wave-like property previously only seen in beams of ...

Vortex phenomena are widespread in nature, from typhoons to ocean currents. In the field of optics, vortex beams, which carry orbital angular momentum, have spiral wavefronts and ring-shaped intensity ...

Researchers have developed a 3D-printed device that generates twisting light beams with orbital angular momentum (OAM), a form of rotational energy that can carry more data than regular beams.

The Fourth Industrial Revolution is driving exponential growth in data transmission, and cost-effective, ultrafast, and compact optical communication technologies are urgently needed to manage the ...

Like soft serve ice cream, beams of atoms and molecules now come with a swirl. Vortex beams made of light or electrons have shown promise for making special types of microscope images and for ...

These vortices could help answer fundamental questions about the inner workings of the subatomic world and be used to enhance a variety of technologies – for example, by providing new capabilities for ...
