As far as particles of light are concerned, the collective is more important than the individual. When they get to decide between two states, they will favor the one that many of their fellow ...

Physicists have engineered photons that behave as if they inhabit a space far richer than the familiar three dimensions, revealing light-like particles with a strikingly high-dimensional character. By ...

What is heat, and what is useful work if a machine consists only of an atom and light particles? In modern quantum technologies, this kind of question connects thermodynamics with quantum physics.

Amplification of light in atmospheric aerosol particles can affect their photochemistry, substantially accelerating sunlight-driven in-particle photochemical reactions, which are major contributors to ...
