Asymptotic temperature dependence of the superfluid density in liquid ${}^4$He

Abstract

In a modified ideal Bose gas model we derive an expression for the temperature dependence of the superfluid fraction in liquid ${}^4$He. This expression leads to a fit formula for the asymptotic temperature dependence that reproduces the data significantly better than comparable formulas.
