Photons are particles of light, or waves, or something like that, right? [Mithuna Yoganathan] explains this conundrum in more detail than you probably got in your high school physics class. While ...

The rich history of research involving photons is celebrated in a supplement to this month's Nature Physics. This is the tenth in the series of Milestones supplements, preceded by others on such ...

Particle detectors play a crucial role in our understanding of the fundamental building blocks of the universe. They allow ...

Two-photon emission (2PE) is a process in which an electron transition between quantum levels occurs through the simultaneous emission of two photons. Two-photon emission is interesting because it ...

This means that scientists think of photons as behaving like both particles and waves, depending on how they're observed. Furthermore, photons are also understood as excitations in an ...
