The surprising experimental observation of a drastic influence of fermionic atoms on the Mott quantum-phase transition of bosonic atom was heavily discussed, as the standard Hubbard model predicts the opposite. We found that the secret lies within the interaction-induced tunneling mediated by the fermionic particles...
