PHYSICS DIVISION
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.
Our mission: To understand the structure, evolution and interactions of the
fundamental constituents of the universe through experimental and theoretical
research along with solving practical problems to advance the interests of the
nation and the world.
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 FRONTIER 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.
