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

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 ...

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 ...

In a mind-warping milestone experiment, scientists have been able to manipulate small numbers of individual photons of light, opening doors for the development of quantum technologies. This research, ...

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

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 ...

“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 ...

For the first time, scientists at the University of Sydney and the University of Basel in Switzerland have demonstrated the ability to manipulate and identify small numbers of interacting photons – ...

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 at Rice University, Houston, Texas, have developed a new way to control light interactions using a specially engineered structure called a 3D photonic-crystal cavity. Their work, published ...
