Scientists at the X-ray free-electron laser SwissFEL have realized a long-pursued experimental goal in physics: to show how ...
Physicists are learning to treat light not as an untouchable beam that simply passes through matter, but as something that can be bent, cloaked, and sculpted at scales smaller than a single wavelength ...
Imperial physicists have recreated the famous double-slit experiment, which showed light behaving as particles and a wave, in time rather than space. The experiment relies on materials that can change ...
