Who we are
The Physics Division builds on ORNL strengths to perform outstanding leadership research for the Nation in nuclear science, isotopes, and related areas. Our focus is in the areas of Fundamental Symmetries, Nuclear Structure Physics, Nuclear Astrophysics, Heavy Ion Collisions, and Isotope R&D and Production.
Through a combination of frontier measurements and world-leading theory, we address questions of critical importance in the basic and applied research communities. Some examples: our measurement of the electric dipole moment of the neutron (nEDM) at the SNS will help solve the riddle of the balance of matter and antimatter in the Universe; our measurement of neutrino-less double beta decay in deep underground labs will help define the New Standard Model; our simulations on the TITAN supercomputer of subatomic nuclei are leading to new insights on the quantum many-body problem; our measurements of heavy ion collisions at the most powerful accelerator labs probes the state of the quark-gluon plasma thought to exist in the early Universe; our production of rare and radioactive samples are used to diagnose and treat cancers as well as to create Tennessine, one of the heaviest elements in the periodic table; our measurements with beams of neutron-rich unstable nuclei probe the properties of exotic nuclei as well as the production of these nuclei in neutron-star mergers and core-collapse supernovae; and our state-of-the-art 3D simulations of these supernovae are redefining our knowledge of these catastrophic stellar events that create and disperse the elements of life.
For these studies, our researchers are developing detectors with breakthrough technologies that have spinoffs in national security, nuclear medicine, and related fields, as well as software techniques that are relevant for quantum computing and hydrodynamic flows.
