A pulse of light sets the tempo in the material. Atoms in a crystalline sheet just a few atoms thick begin to move—not ...

Researchers built a silver-grooved chip that channels laser energy into nanometer-spaced peaks, beating the diffraction limit and aiding light-matter studies.

Sir Chandrasekhara Venkata Raman and his student Nagendra Nath published a series of papers in 1936 on the diffraction of light by a liquid in the field of a high frequency sound wave. This was ...

A flash of light has turned a sheet of atoms into a dance floor. In a feat of precision physics, researchers from Cornell and ...

A U.K.-Portuguese research group is proposing a new solar cell design based on diffraction gratings – optical components that split and diffract light into several beams. They claim this could lead to ...

Increasingly complex applications such as artificial intelligence require ever more powerful and power-hungry computers to run. Optical computing is a proposed solution to increase speed and power ...

(Nanowerk News) Until recently, it was widely believed among physicists that it was impossible to compress light below the so-called diffraction limit (see fact box), except when using metal ...

Researchers at Harvard University and Jiangsu University developed a technique for not only identifying infected cells, but also tracking the infection over time as the cells developed. They published ...

BRYAN, Texas (KBTX) - In the midst of a foggy Thursday morning, an arc of white stretched above the horizon, catching the eye ...
