16. Alternatively, one can fix the value of T to the initial value and obtain an equivalent set of equations, as in the work of Pedri et al. [15]. The choice made in the present work is particularly convenient if the expansion starts from a T = 0 configuration.
17. Note that eq. (10) can also be obtained by starting strictly from the Boltzmann H-theorem.
18. In practice, the T = 0 approximation is compatible with the assumption that the gas is non-superfluid, the critical temperature for the BCS transition being exponentially small in a dilute gas.
