Chiral phonons are groups of atoms that move in a circular direction when excited by an energy source, such as heat. As the phonons move through a material, they propagate that circular motion, or angular momentum, through the material. The angular momentum serves as the source of spin, and the chirality dictates the direction of the spin, enabling spin control in spintronics. https://phys.org/news/2026-08-electric-field-reverses-phonon-chirality.html Condensed Matter Wed, 05 Aug 2026 15:00:06 EDT news705151382 Quantum technologies promise revolutionary advances in computing, sensing and information processing.
