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

It may sound like an oxymoron, but this massive nanoparticle made up of 7,000 sodium atoms is the largest to exhibit such ...

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 ...

A cluster of 7,000 sodium atoms has just been coaxed into behaving as a single, ghostly wave, stretching quantum weirdness into a realm that starts to look uncomfortably like everyday matter. Instead ...

Antimatter isn't just made of antiparticles, it's also made of waves. Now we know that this holds true even at the level of a single antimatter particle. Physicists have known for a long time that ...

Schematic of the MIT experiment: Two single atoms floating in a vacuum chamber are illuminated by a laser beam and act as the two slits. The interference of the scattered light is recorded with a ...

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 ...

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.
