We study ground-state properties of ultracold fermionic mixtures with strong mass imbalance in one and two-dimensional optical lattices through large scale numerical simulations of the attractive Falicov-Kimball model in harmonic confining potentials. In the one-dimensional case, we observe a formation of insulating atomic-density-wave domains at low particle fillings and a coexistence of insulating and metallic domains at intermediate and large particle fillings. Moreover, we show how the formation of metallic regions is reflected in the momentum distribution of the light atoms. In two dimensions, we find a rich spectrum of density-wave patterns including the homogeneous distributions, the axial striped distributions, the labyrinthine phases as well as the segregated phases.
