The Two-Fluid Theory for Superfluid Hydrodynamics and Rotational Motion
Phil Attard
The two-fluid theory for superfluid hydrodynamics is derived from the fountain pressure result that condensed bosons move at constant entropy and are driven by the chemical potenti…

Information vs Thermodynamic Entropy
Phil Attard
The Shannon information is shown to be different to the thermodynamic entropy, and indifferent to the Second Law of Thermodynamics.
