Physicists at NYU have discovered a new type of time crystal—an exotic state of matter whose particles rhythmically “tick” while levitating on sound waves.

“Our system is remarkable because it’s incredibly simple,” said paper author and physicist David Grier of New York University ...

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

A microscopic clump of sodium has become the largest object ever to be observed as a wave, improving upon previous records by thousands of atoms. Quantum physics defines particles in terms of waves, ...

Acoustic tweezers use sound waves to create a potential-energy well that can hold an object in place – they are the acoustic ...

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 ...

Dark matter is a type of matter that is predicted to make up most of the matter in the universe, yet it is very difficult to ...

Counter-intuitive finding suggests particle formation from natural and anthropogenic organic compounds might increase during extreme heat events ...

The ‘PST Art: Art & Science Collide’ exhibition features Larry Bell, Fred Eversley, Claire Falkenstein, Man Ray and Robert Irwin, among others. Sections of the show may focus on math and what some may ...

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 ...
