Supersolid
|
A supersolid is a spatially ordered superfluid.
Phase diagram for 4He |
When quantum fluids, like helium-4, are cooled below a certain characteristic temperature, they undergo the superfluid transition and enter a state of 0 viscosity. It has been theorised that quantum fluids can undergo a similar transition from the solid phase.
