Ultra-cold atom gases trapped in an optical lattice are now poised to make strong contributions to resolving outstanding questions in condensed matter physics. In these experiments, atom gases are cooled to temperatures below a millionth of a degree of absolute zero and confined in a crystal of light. I will talk about how we are using this system to simulate models relevant to dirty superconductors and highlight some recent results, including the first experiments in a fine-grained disordered lattice and the observation of a disorder-induced superfluid-to-insulator transition. I will also give a brief overview of new experiments using spin-dependent lattices to develop primary thermometry in the strongly correlated limit.
