For more than a century, schoolbook physics has divided matter into neat categories like solid, liquid, gas, and plasma. A wave of recent experiments is now tearing at those boundaries, revealing ...

Discovering a new class of matter in the lab of Chiara Daraio at Caltech, researchers have identified a type of material that uniquely responds to stress, behaving like a fluid under some conditions ...

Supersolid light, a newly discovered phase of matter, represents a groundbreaking leap in our understanding of physics. This phenomenon combines properties of both solids and superfluids, resulting in ...
