Ranch dressing is actually a fifth state of matter known as soft matter. Soft matter can have properties of both liquids and ...

You probably learned in school that there are three states of matter: solid, liquid and gas. Think ice cube, a puddle of water and fog. Maybe you also learned about a fourth state, known as plasma .

At first, the photons settle into a state with zero momentum, but as this state 'fills up', pairs of photons begin to spill into the two adjacent states. This causes the polaritons to condense into ...

For the first time, researchers transformed light into a quantum crystalline structure to create a "supersolid" that's both solid and liquid at the same time. Here’s what that means, and why it's such ...

There are three main states of matter: solid, liquid and gas. When a substance changes state, this is a physical change because no new substances are produced and the change is reversible.

With properties of a superfluid but with a crystalline structure, supersolids have previously only been observed in ultracold condensates—until now.

A supersolid is a special type of matter that flows like a liquid but has a solid-like structure. Until now, scientists had ...
