    • The scattering length can be replaced by a function of the relative momentum in order to get an advanced energy dependence of the scattering phase shift. In case of a constant a, one accounts for a trivial energy dependence δ (k) =arctan ka, which is valid for broad Feshbach resonances and nonresonant scattering.

    • For the validity of this approximation it is important that the variation in the lattice potential is negligible over the range of the real interatomic potential. For more discussion on the validity of the pseudopotential, see, e.g., Ref..

    • The lowest state at positive scattering length is the molecular bound state. Because we aim to describe scattering between atoms here, we use the one-but-lowest symmetric state, with s= { 3,0,0 }.
