Probable observation of a supersolid helium phase
Article Abstract:
The study proposes theoretically that superflow can occur in the solid state of helium. Delocalized vacancies and defects are expected to be present in crystalline solid helium, owing to quantum mechanical fluctuations, even in the limit of zero temperature.

Low-temperature shear modulus changes in solid [He.sup.4] and connection to supersolidity
Article Abstract:
Supersolidity and the changes observed in the shear modulus of [He.sup.4] at low-frequencies and strains are discussed. Solid [He.sup.4] is found to be completely independent of the pressure differences and persistent currents.

Supersolid helium
Article Abstract:
It is an uncommon phenomenon that helium-4 enters a superfluid state and flows without friction, which makes superfluidity. Description about helium's superfluidity is mentioned.
