Abstract:
General conditions for thermodynamic stability of a superfluid are studied in the full space of thermodynamic variables, including (along with the conventional thermodynamic coordinates such as pressure and temperature) superfluid motion velocity and momentum density. The stability conditions lead to the thermodynamic inequalities that replace the Landau superfluidity criterion at nonzero temperatures.
