Experiment shows phonons mix in such a way to allow classification as 'bosonic' particles

(Phys.org)—A team of researchers working at Osaka University in Japan has devised an experiment that gave results showing that phonons mix in such a way that they can be now be classified as 'bosonic' particles. Dave Kielpinski with Hewlett Packard Laboratories, offers a News & Views piece on the work done by the team and explains how it relates to work done with photons and other quantum particles.
