Calculations intended to feel out the interactions between light and the material that produces it may inadvertently describe the photon's outline, revealing its shape in unprecedented detail. A new ...

Two ghostlike particles, neutrinos and photons, are emerging as unlikely combatants in a quiet revolution in physics. New calculations suggest these nearly intangible entities may interact in extreme ...

Lighten up, people: a fascinating new paper has dropped that describes the shape of a single photon, the smallest possible form of energy in an electromagnetic field that we commonly know as light.

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 ...

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 ...

The increasing demand for advanced optoelectronic devices necessitates the development of materials that can efficiently absorb and manipulate light at the nanoscale. This research explores the unique ...

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 ...
