It has later been shown that Landau's two-fluid model can be rigorously derived from a one-fluid model within the classical fields approximation. Assuming a separation of scales exists between the slowly varying, large-scale, background (condensate) field, and the short rapidly evolving excitations, a full description of the kinetics between the condensate and the thermal cl","authors_text":"Hayder Salman, Natalia G.
