Abstract : We study optical lattice systems, in which rapid experimental progress and tremendous potential for quantum emulations provide many opportunities for investigating open questions in condensed matter physics, and possibly quantum computing. We study the many-body effects in two- and three-dimensional Hubbard-like models, focusing on long-wavelength collective modes, such as spin-density waves, and other matter-wave properties resulting from particle interaction and quantum coherence. The second focus is on molecular physics, where we aim to achieve an accurate, robust many-body paradigm for predicting properties and mechanisms of small molecules. Success of the research can contribute a powerful and yet heretofore largely missing third (computational) component for these areas, and help accelerate the realization of novel applications and new technological capabilities of interest to the Army and beyond.
