Supersolid - Definition and Overview

A supersolid is a spatially ordered superfluid.

Phase diagram for 4He

When quantum fluids, like ⁴He, 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.
