Spontaneous coherence is one of the most dramatic signatures of collective quantum behaviour on large scales. Such spontaneous coherence arises when, below a critical temperature, a phase transition occurs to a state with a macroscopic occupation of a single quantum state. The idea of such a phase transition was first considered for non-interacting particles by Bose and Einstein (i.e. Bose-Einstein condensation), however the general principles apply far more widely. Until recently, the experimental study of spontaneous coherence had been restricted to cold atomic gases, liquid helium and superconductors. However, the last few years have shown huge progress in several distinct but related examples of solid state systems.
