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.
A material that is capable of the “reverse diffraction” of light and that is inspired by butterfly wings has been made by researchers in the US. The structure combines features of the butterfly’s ...
