How to Control Heat with Hypersound

In solids, sounds and heat are entangled in the form of a quasiparticle called a phonon. Researchers at the SHINES center showed that they could control phonons by confining them in a field of nanowires. This finding will have major implications for managing heat in nanoscale electronics.
