A derivation of the hydrodynamical equations for superfluid helium

  • T. C. Lubensky


A purely macroscopic and unambiguous derivation of the hydrodynamical equations for superfluid helium is presented. The existence of a condensate wave function is inserted in the beginning as an essential in the description of the thermodynamic state of superfluid helium, and the derivation is carried out in the frame in which the normal velocity is zero.
