    • -1=1.11 for the polaron-to-molecule transition, 30% off the T-matrix prediction. This difference is due to the overestimate of the molecule-fermion repulsion by the T-matrix approximation, which yields 8/3a for the molecule-fermion scattering length in place of the exact value 1.18a [25], thus making the molecule formation in a Fermi sea enviroment less convenient.

    • The value 1.60 for the critical coupling in the limit nB→0 is reached with a weak re-entrant behavior of the critical coupling vs imbalance, occurring at imbalances larger than those reported in Fig. 1.

    • Our preliminary calculations for mB*mF indicate that also in this case the critical coupling for a single boson governs the quantum phase transition. In particular, at the experimentally relevant ratio mB/mF=87/40, the critical coupling is in the range 1.3-1.5 at finite boson densities, its value for a single boson being 1.28.
