Implementation of a Classical Theory for Superfluids ()
ABSTRACT
The superfluidity of helium-4 is explained until
today by a quantum theory: the Bose-Einstein condensation. This theory is
rather satisfactory in describing the superfluid state of helium-4 because this one
is a system made up of bosons (particles of integer spin). However, the
discovery of the superfluidity of helium-3 in 1971 called into question the
veracity of this quantum theory. In fact, helium-3 being a system composed of
fermions (particles of half-integer spin), it cannot be subject to
Bose-Einstein condensation. It is to correct this deficiency that we introduce
here a classical (non-quantum) theory of superfluids. This new theory makes no
difference between the λ transition of bosons and that of fermions. It is
based on a fundamental law: “in a superfluid, density is conserved”. In this
work, we have shown that this simple law explains not only the zero viscosity
of superfluids but also the surprising phenomena observed in the superfluid
state, I quote the liquidity of helium at normal pressure down to 0 K,
vaporization without boiling, high thermal conductivity, the fountain effect,
the ability to go up one side of the wall of a container to come down on the
other side and the existence of a critical velocity.
