Topological phonons: Where vibrations find their twist

[gabriele1]

A team of international researchers has discovered that the quantum particles responsible for material vibrations, known as phonons, can be classified using topological principles. Their study, which analyzes the phonon structures of thousands of materials, found that around half exhibit topological phonons. This finding has significant implications for the thermal and electrical properties of solid materials and could lead to new applications like surface superconductivity and heat management.
