Two ghostlike particles, neutrinos and photons, are emerging as unlikely combatants in a quiet revolution in physics. New ...

Scientists at the X-ray free-electron laser SwissFEL have realized a long-pursued experimental goal in physics: to show how ...

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 ...

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 ...

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 ...

A team of researchers has successfully demonstrated nonlinear Compton scattering (NCS) between an ultra-relativistic electron beam and an ultrahigh intensity laser pulse using the 4-Petawatt laser.

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 ...
