Even for scientists who have dedicated their lives to understanding gravity, the force’s relentless downward pull is sometimes a drag. Consider, for instance, the researchers who study Bose-Einstein ...

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

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 ...

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 ...

Experiments reveal that metallic nanoparticles thousands of atoms wide can exist in quantum superposition, providing a stringent test of quantum mechanics. Matter wave in the spotlight: The image ...

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 ...

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.
