Using a quantum phase transition to efficiently produce heteronuclear molecules

An atomic Bose–Fermi mixture was driven through a quantum phase transition by varying an applied magnetic field to tune the interspecies interactions. This approach enabled the efficient generation of sodium–potassium molecules in the quantum degenerate regime.
