Ever since quantum mechanics first described particles, like electrons, as rippling waves, researchers have wondered if those ...

Columbia University researchers report the first observation of electron waves trapped in place inside a two-dimensional ...

Yet on a fundamental level, we still don’t understand what quantum mechanics is saying about how the world works. Any ...

Scientists at Columbia University have found that electron waves can remain trapped near atomic defects in a metal, despite ...

Electron microscopy tracked dark zeros in a wave field moving faster than light in vacuum, without transmitting energy or ...

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 have long grappled with a fundamental question: what exactly is light? Is it a wave, flowing like ripples across water, or is it made up of tiny particles, like miniature paintballs zipping ...
