Bose–Einstein condensation of photons in an erbium–ytterbium co-doped fiber cavity, Published online: 14 February 2019; doi:10.1038/s41467-019-08527-0

Bose–Einstein condensates were demonstrated at low temperatures, mostly with ultracold bosonic atoms. Here, the authors demonstrate BEC of photons in a standard 1D erbium–ytterbium co-doped fiber cavity at, below and above room temperature.
