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 ...

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

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 – ...

Chiral metasurfaces can strongly twist the polarization of light, but how this process unfolds in space and time has been unclear. Scientists in China have now used ultrafast electron microscopy and ...

“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 ...

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 ...

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 ...

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