Abstract:

There might be amorphous solid He-4 formed in around 6 nm (diameter) pore as reported recently. By treating the solid He-4 in confined nanodomains locally as an amorphous matter and using the Eyring's model together with the activation energies and volumes, we can observe sudden changes of the shearing stresses (which relate to the resistance) as well as shear viscosities (which relate to the rigidity) at corresponding onset temperature of solid He-4. We demonstrated that there might be almost frictionless transport of locally amorphous solid He-4 in confined nanopores at temperature  ~ 0.08 K.

Keywords: Vacancies, shear viscosity, transition state.
