    • HFB can be considered as a variant of the Girardeau-Arnowitz approach [21]. As a consequence, a generalization of HFB without breaking the U(1) symmetry is possible but goes beyond the scope of the present paper.

    • The potential (3) supports a bound state. As a consequence, HFB equations (7)-(9) can lead to nontrivial solutions: Φ=0 whereas ñ ≠ 0 corresponding to a molecular condensate composed of dimers (see Ref. [23] for the 3D case). Condition (12) allows avoiding this problem.
