We report on site-resolved imaging of various fermionic many-body states of ultracold Li-6 in a square optical lattice, including metallic, Mott-insulating and band-insulating phases. The insulating states show a suppression in the single-site occupation variance and a spatially constant filling fraction. A comparison to theory shows that the system is in global thermal equilibrium with fitted global entropies of 1.0 kB. We also report on our most recent progress towards probing magnetically ordered quantum states with the quantum gas microscope.
