The two-fluid model with superfluid entropy
R. Schaefer, T. Fliessbach
The two-fluid model of liquid helium is generalized to the case that the superfluid fraction has a small entropy content. We present theoretical arguments in favour of such a small…

A new sound mode in liquid Helium 4?
R. Schaefer, T. Fliessbach
This letter is based on the hypothesis of a small entropy content of the superfluid fraction of liquid helium. We show that such a superfluid entropy gives rise to a new sound mode…
