Abstract: Under very high pressure, pockets of vacuum may be created around super solid ⁴He crystals. Crystals of ⁴He may flow through pockets of vacuum, one behind the other, and since the flow in vacuum will be frictionless and ⁴He atoms being bosons can swap positions, the flow may appear to be superfluid. Thus, the crystals will not be flowing into each other, but will flow one behind the other, and since they are identical, the flow may appear as superfluidity of solid ⁴He. The thermodynamic properties of the crystal, phase transition in solid ⁴He and supersolid ⁴He , zero-point energy and the size of the region in which the particle is confined under high external pressure, have been studied.
