Photons, for centuries both a puzzle and a tool, continue to help scientists illuminate nature at the smallest and largest scales. Photons, the fundamental particles of the electromagnetic field that ...

Scientists working on CERN’s Compact Muon Solenoid (CMS) experiment have published the latest data in their search for a long-lived exotic particle known as the dark photon. Dark photons (also called ...

Scientists have made discoveries about light particles known as photons that could aid the quest for fusion energy. Both literally and figuratively, light pervades the world. It banishes darkness, ...

Alessandro Fedrizzi is in the School of Engineering & Physical Sciences, Heriot-Watt University, Edinburgh EH14 AS, UK. Read the paper: Energy–speed relationship of quantum particles challenges ...

Thousands of particles of light can merge into a type of 'super photon' under suitable conditions. Physicists call such a state a photon Bose-Einstein condensate. Researchers have now shown that this ...

Physicists have forced light to behave like electrons trapped in a magnetic field, reproducing the quantum Hall effect with photons for the first time. The experiment, carried out on an optical fiber ...
