Researchers have demonstrated that a nanoparticle of 7,000 sodium atoms can act as a wave, creating a record-setting ...

Physicists have finally watched positronium, a short‑lived atom made of an electron and its antimatter twin, behave like a rippling quantum wave instead of a tiny billiard ball. In a set of ...

Imperial physicists have recreated the famous double-slit experiment, which showed light behaving as particles and a wave, in time rather than space. The experiment relies on materials that can change ...

Researchers from the University of Vienna have reported quantum interference in metallic nanoparticles. These little spheres were made of between 5,000 and 10,000 sodium atoms and measured about 8 ...

As high school students see in experiments with water waves, and we observe and use with light waves in many optical devices, interference is a fundamental property associated with wave-like behavior.

At the smallest scales of nature, the rules of the world shift in ways that can feel unsettling and beautiful at the same ...
