    • It is easy to see that c2 =0 in the BEC limit implying a vanishing pair size. This is a consequence of the relation ns (q) that holds for a weakly interacting BEC described within Bogoliubov theory. The latter is appropriate in the molecular limit of the BCS-BEC crossover with dimer-dimer scattering length add =0.6a.

    • Note that the Weizsäcker inhomogeneity correction has precisely the form of the quantum pressure contribution in the Gross-Pitaevskii theory of a Bose superfluid, which describes the ground state of the BCS-BEC crossover in the molecular limit. Accounting for the factors 2 in the associated Bose mass or density, the corresponding value of b in this limit consistent with Eq. is b=1/16=0.0625.
