A quantum state of matter has appeared in a material where physicists thought it would be impossible, forcing a rethink on the conditions that govern the behaviors of electrons in certain materials.
The discovery, made by an international team of researchers, could inform advances in quantum computing, improve electronic efficiencies, and deliver enhanced sensing and imaging technologies.
The state, described as a topological semimetal phase, was theoretically predicted to appear at low temperatures in a material composed of cerium, ruthenium, and tin (CeRu4Sn6), before experiments verified its existence.
