Information processing in today’s computers is done almost exclusively by charges (electric currents). Photons, albeit they are ideal for information transmission, never became a mainstream technology ...

In the famous double-slit experiment, an interference pattern consisting of dark and bright bands emerges when a beam of light hits two narrow slits. The same effect has also been seen with particles ...

Scientists studying particle collisions at the Relativistic Heavy Ion Collider (RHIC) usually capture what happens when atomic nuclei smash into one another at nearly the speed of light. But even when ...

In the quirky quantum world, particles can be affected by forces that they never directly encounter. A classic example is the Aharonov–Bohm (AB) effect, where electrons are affected by a magnetic ...

This interference pattern was the evidence Young needed to determine that light was a wave and not a particle as Newton had suggested. But that is not the whole story. Light is a little more ...

Light is well known to exhibit both wave-like and particle-like properties, as imaged here in this 2015 photograph. What's less well appreciated is that matter particles also exhibit those wave-like ...
