Numerical Evaluation of the Two-Fluid Hydrodynamic Coefficients and Temperature-Dependent Second Sound in a Finite-Temperature Bose Gas

We present a numerically stable evaluation of the two-fluid hydrodynamic coefficients for a dilute Bose gas of rubidium-87 at finite temperature. Our contribution is threefold: (i) we compute the condensate gradient stiffness $B$, the entropy density $S$, and the specific heat $c...
