Quantum degenerate gases are formidable systems to shine light on fundamental quantum phenomena occurring at extremely low temperatures, such as superconductivity and superfluidity. In combination with optical lattices and scattering resonances, degenerate gases give rise to strongly correlated systems, enriching even further the breadth of phenomena that can be directly probed. Indeed, the pioneering experiment on the superfluid to Mott-insulator transition [1] has shown how physical models long studied in the field of condensed matter can be realized almost ideally. With two different atomic species, the wealth of quantum phases grows to a daunting complexity [2], only marginally explored by experiments. Actually, experiments with heteronuclear mixtures in three-dimensional (3D) optical lattice have been performed very recently only for Fermi-Bose systems [3, 4], while Fermi-Fermi and Bose-Bose mixtures are yet uncharted territory. The importance of mixtures in optical lattices is hardly overstated: association of dipolar molecules [5], mapping of spin arrays [6], schemes for quantum calculation [7], and implementation of disorder [8] represent only a few major research lines that potentially will greatly benefit from such systems. In particular, Bose-Bose mixtures seem well suited for all these purposes, provided that collisional losses are adequately suppressed. This work reports the first realization of a degenerate Bose-Bose heteronuclear mixture in a 3D optical lattice. Exploiting the large mass difference, we investigate the regime where one species lies well in the superfluid domain, while the other exhibits the disappearence of the interference pattern usually associated with the transition from a superfluid to a Mott insulator.
