The quantum tunneling of correlated atoms in an optical lattice is investigated in the presence of ac-driving fields. The effective Hamiltonian with density-dependent hopping rates are deduced. The migration of a correlated atoms in 1D and 2D lattices can be realized. Based on this mechanism, we propose a method to create two-partite entanglement. Our model may provide applications in quantum computing and quantum information in ultracold atoms.
