New stability rules distinguish quantum phases of matter that an older method wrongly groups together
Physicists at the University of Illinois have developed a new framework to classify nonequilibrium quantum phases of matter. This method allows researchers to distinguish between quantum phenomena that were previously grouped together by older classification schemes.
Why it matters
Advancing the classification of quantum phases is essential for the development of future quantum computing applications.

Credit: The Grainger College of Engineering at the University of Illinois Urbana-Champaign Most of us recognize basic phases of matter and their properties: solids maintain their shape, liquids flow freely with constant volume, and gases expand to fill their container. Quantum phases, on the other hand, are much harder to categorize, overturning traditional notions of what a phase even is and forcing physicists to rethink their definitions.
