In condensed matter physics, a supersolid is a spatially ordered (i.e. solid) material with superfluid properties. In the case of helium-4, it has been conjectured since the 1960s that it might be possible to create a supersolid.[1] Starting from 2017, a definitive proof for the existence of this state was provided by several experiments using atomic Bose–Einstein condensates.[2] The general conditions required for supersolidity to emerge in a certain substance are a topic of ongoing research.
