Electric field reverses phonon chirality and spin direction in ferroelectric crystal

Electric field reverses phonon chirality and spin direction in ferroelectric crystalWorldPing

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.
