Exploring the Potential of Phonons as a Chiral Force
In recent years, scientists have been debating the chirality of phonons. Phonons are quasiparticles created through the collective motion of atoms in a crystal lattice. These particles have been found to possess both left- and right-handed properties, which has led to an ongoing discussion of how they should be classified. In a new study, scientists have used a combination of theoretical and experimental techniques to gain a better understanding of the chirality of phonons. They found that phonons are indeed chiral, with properties that depend on their direction of propagation. This discovery could have important implications for future research in the field of phonon-based materials.
