We study ultracold gases loaded into artificial crystals of light known as optical lattices. The behavior of ultracold atoms in optical lattices is similar to that of electrons in solids. Because of that, ultracold atoms can provide clean realizations of models from condensed matter which can be studied in a highly controlled environment. We developed a novel microscopy technique that allows us to image atoms in optical lattices with submicron and single-site optical resolution. Our experiments with bosonic rubidium and fermionic lithium are at the interface of atomic physics, condensed matter physics and quantum information.
