    "abstract": "We, based on the photoassociation of fermion atoms into bosonic molecules,\npropose a scheme to create the steady entanglement between the atom state and\nthe molecule state inside an optical lattice. The stability of entanglement\nstate is guaranteed by sweeping the frequency of Ramman laser beam through\nresonance according to the second Demkov-Kunike (DK2) nonadiabatic transition\nmodel\\cite{DK,models}. The probability amplitude of each components can be\nprecisely controlled by adjusting the sweeping parameter.",
