"Researchers investigating the creation of biexcitons noticed an unexpected drop in energy when creating multiple biexcitons in gallium arsenide, leading to the discovery of a new state of matter; the dropleton. Excitons are quasi-particles created when a photon knocks an electron loose from a material, causing an electron hole. If the forces of other charges nearby keep the electron close enough to the hole a state known as an exciton forms where the combined electron and hole act together as though they are a single particle. Biexcitons consist of two of these quasi-particles and collectively behave like a molecule. In this discovery several excitons are behaving together in a 'quantum fog' and behave like a droplet, hence the name.

See the article in Nature for more information."

    actually the more I think about that the more I am inclined to suspect that "high temperature" for dropletons might be around 1000K. But this is the first time I heard about them, so you can see how wild is are my guesses. If it's indeed 1000K, then it could be really interesting to investigate and may yield some useful applications.
