Abstract
We show that by loading a Bose-Einstein condensate (BEC) of two different atomic species into an optical lattice, it is possible to achieve a Mott-insulator phase with exactly one atom of each species per lattice site. A subsequent photo-association leads to the formation in each lattice site of one heteronuclear molecule, which possesses a large electric dipole moment. The melting of such dipolar Mott-insulator creates a dipolar superfluid, and eventually a dipolar BEC.
