"Dark photon" theory says light's interference patterns may emerge from quantum particles, not waves, upending centuries of ...

Does light behave more like a particle, or like a wave? Today we know the surprising answer. Here's why it took so long to get there. When you purchase through links on our site, we may earn an ...

Aurorae are generated by charged particles originating from Earth's magnetosphere and the solar wind colliding with and exciting particles in Earth's upper atmosphere, which then emit light as they ...

The use of atomic clocks could help bring cosmology and astrophysics "down to Earth" by allowing scientists to investigate the mysteries of dark energy and dark matter in the lab. When you purchase ...

Polaritons offer the best of two very different worlds. These hybrid particles combine light and molecules of organic material, making them ideal vessels for energy transfer in organic semiconductors.

Cherenkov radiation is a form of energy that we can perceive as a blue glow emitted when the electrically charged particles that compose atoms (i.e. electrons and protons) are moving at speeds faster ...

Researchers from the Faculty of Physics at the University of Warsaw, ETH in Zurich and the University of Cambridge have synthesized and analysed active microparticles self-propelling in a fluid and ...
