Photons are massless quantum particles that form light. They travel at incredible speeds and interact with various forms of matter. The emission of photons from atoms and molecules can lead to an ...

Researchers have designed a new device that can efficiently create multiple frequency-entangled photons, a feat that cannot be achieved with today's optical devices. The new approach could open a path ...

Operating at room temperature, this nanoscale device leverages silicon photonics to achieve high-performance spin control, ...

Within our comfortable world of causality we expect that reactions always follow an action and not vice versa. This why the recent chatter in the media about researchers having discovered ‘negative ...

“Negative time” might sound like science fiction, but an international team of theorists and experimentalists has determined that a photon can, in fact, spend a negative amount of time in an excited ...

GlueX The spectrometer at Jefferson Lab was used to study the behaviour of gluons within nuclei. (Courtesy: Jefferson Lab/Aileen Devlin) A new experiment has offered the clearest view yet of how ...
