THEORY OF SUPERFLUIDITY IN HELIUM- A REVIEW

Abstract

In nature the inert gas helium exists in two forms, isotopes, with fundamentally different properties. The study of superfluidity and its effect on the property of helium liquid is considered to be principle interest of the researcher from the last century. In this paper a brief account of the property of helium isotopes and the physics involve in the superfluidity of ³He and ⁴He are being discussed. Also listed in this paper are different methods suggested and work done by various research groups to explain superfluidity and its related property in liquid helium.
