The theories that led to physicists Thouless, Haldane, and Kosterlitz being awarded the Nobel Prize in physics, are guiding today’s quantum physicists at ORNL in their search for materials of the future. (Image credit: ORNL/Jill Hemman)

The theories recognized with this year’s Nobel Prize in Physics underpin research ongoing at the Department of Energy’s Oak Ridge National Laboratory, where scientists are using neutrons as a probe to seek new materials with extraordinary properties for applications such as next-generation electronics, superconductors, and quantum computing.

The SNS LINAC is the most powerful proton-pulsed accelerator in the world.
The first of its kind superconducting linear particle accelerator (LINAC) built for the Spallation Neutron Source (SNS) at the Department of Energy’s Oak Ridge National Laboratory is now celebrating 10 years of successful operations. The world-leading machine, which took 7 years...

While trying to fatten the atom in 1938, German chemist Otto Hahn accidentally split it instead. This surprising discovery put modern science on the fast track to the atomic age and to the realization of technologies with profound potential for great harm or great help. Altho...

The image above shows the chain of the studied calcium isotopes. The “doubly magic” isotopes with mass numbers 40 (Ca-40) and 48 (Ca-48) exhibit equal charge radii. The first measurement of the charge radius in Ca-52 yielded an unexpectedly large result.

For decades nuclear physicists have tried to learn more about which elements, or their various isotopes, are “magic.” This is not to say that they display supernatural powers. Magic atomic nuclei are composed of “magic” numbers of protons and neutrons—collectively called nucleons—such as 2, 8, 20, and 28.

Since the discovery of high-temperature superconductors — materials that can transport electricity with perfect efficiency at or near liquid nitrogen temperatures (minus-196 degrees Celsius) — scientists have been working to develop a theory that explains their essential physics.
In conventional, low-temperature superconductivity (left), so-called Cooper pairing arises from the presence of an electron Fermi sea. In the pseudogap regime of the cuprate superconductors (right), parts of the Fermi sea are “dried out” and the charge-ca
When physicists Georg Bednorz and K. Alex Muller discovered the first high-temperature superconductors in 1986, it didn’t take much imagination to envision the potential technological benefits of harnessing such materials.
