Scientists call this phenomenon wave-particle duality. The term applies to elementary particles such as electrons and photons ...

Ever since quantum mechanics first described particles, like electrons, as rippling waves, researchers have wondered if those waves could be trapped in place. Writing today in Science a century later, ...

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 ...

Quantum interference, in particular, plays a key role. It occurs when different pathways that a molecule can take overlap, resulting in specific patterns of interaction: some pathways amplify each ...

In physics, many people get discouraged by the 'equation representing a sine wave' that appears at the very beginning of the ...

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