A Twist in the Lattice: Controlling 'Spinning' Sound
Physicists have directly observed chiral phonons—atomic vibrations carrying angular momentum—within Lithium Niobate crystals. This discovery permits the electrical manipulation of these 'spinning' quasiparticles, offering a novel method to control magnetic properties within the emerging field of chiral phononics.
