Probing (dis-)order with binary atomic mixtures in optical lattices

Ultracold atomic quantum gases in optical lattices allow for fundamental studies in condensed-matter physics, including strongly-correlated many-body systems. My talk will focus on possibilities with two-component mixtures of bosonic atoms in lattices whose depth for each component can be independently controlled. In recent experiments, we have explored the effects of atomic impurities on coherence and transport in one-dimensional Bose gases, including the formation of a strongly correlated glassy phase. We have also studied elastic and inelastic 1D atom scattering from crystalline atomic structures, establishing matter-wave Bragg diffraction as a novel tool to detect spatial long-range order.
