Harnessing Chiral Phonons Unlocks Quantum Transformation and Magnetic Phenomena

Researchers at Rice University have discovered that when the atomic lattice in a rare-earth crystal vibrates in a corkscrew-shaped motion called a chiral phonon, the crystal becomes magnetized. By exposing cerium fluoride to ultrafast pulses of light, the spins of electrons align with the atomic rotation, resulting in magnetization. This effect, known as spin-phonon coupling, has potential applications in developing novel magnetic and quantum materials. The study provides insights into the interaction between chiral phonons and material properties, contributing to the understanding of quantum effects in solids.
