Condensed-matter physics: First glimpse of the orbiton

Philip B. Allen1 & Vasili Perebeinos1

Top

Crystals are host to a variety of disturbances, which show up as waves or particles. Physicists think they may have seen a new type of disturbance called the orbiton.

On page 180 of this issue, Saitoh et al.1 present evidence for the observation of a new particle in a solid. Although predicted to exist, this first sighting of the orbiton should allow it to join the list of 'particle excitations' found in solids, such as electrons, holes, phonons, magnons, excitons and plasmons.
