Our program is focused on the low-energy structure of atomic nuclei. The challenge is to understand nuclear collective phenomena, like rotations and vibrations, in terms of interactions between the constituent nucleons. Both microscopic (shell-model) and the macroscopic (collective) pictures are believed to be applicable because of the coexistence of regular motion, like that associated with closed orbits in classical physics, and a background of irregular or chaotic behavior, as for open classical orbits. Algebraic (group theory), many-body, and high-performance computing methodologies are combined in a study of strongly deformed nuclei. Examples include enhanced electromagnetic transition rates, superdeformed configurations, and single as well as double beta decay strengths in rare earth and actinide nuclei. Another area of interest is nonlinear phenomena, in particular, analytic and numeric tools for dealing with nonlinear processes, consequences of nonlinear couplings in physical systems, and how nonlinear effects are manifest in atomic nuclei.
