Microscopic construction of the two-fluid model for superfluid helium-4
Using a system of Heisenberg's equation of motion for both the normal and the anomalous correlation functions a two-fluid hydrodynamics for superfluid helium-4 was constructed. The method is based on a gradient expansion of the exact equations of motion for correlation functions about a local...

| description |
Using a system of Heisenberg's equation of motion for both the normal and the anomalous correlation functions
a two-fluid hydrodynamics for superfluid helium-4 was constructed. The method is based on a gradient
expansion of the exact equations of motion for correlation functions about a local equilibrium together with
explicit use of the local equilibrium statistical operator for superfluid helium in the frame of reference, where
condensate is in the state of rest. |
