We are a collection of nuclear theorists with a main research goal of forming a quantitative bridge between our understanding of nuclear physics and quantum chromodynamics (QCD), the fundamental theory of strong interactions.
This will allow for crucial theoretical input for the quest to probe the limits of the Standard Model through precision tests of its fundamnetal symmetries in low-energy nuclear environments. These include among others, experimental searches for neutrinoless double beta decay, permanent electric dipole moments in nucleons and nuclei, direct dark matter detection and hadronic parity violation.
This research requires efficient use of state of the art high performance computers. To conduct this research, we receive support from US Department of Energy (DOE) Office of Advanced Scientific Computing Research and the Office of Nuclear Physics, as well as our home institutions.
