A material’s spins, depicted as red spheres, are probed by scattered neutrons. Applying an entanglement witness, such as the QFI calculation pictured, causes the neutrons to form a kind of quantum gauge. This gauge allows the researchers to distinguish between classical and quantum spin fluctuations. Credit: Nathan Armistead/ORNL, U.S. Dept. of Energy

A team led by the U.S. Department of Energy’s Oak Ridge National Laboratory demonstrated the viability of a “quantum entanglement witness” capable of proving the presence of entanglement between magnetic particles, or spins, in a quantum material.

Unexpected results from a neutron scattering experiment at the Department of Energy’s Oak Ridge National Laboratory could open a new pathway for the synthesis of novel materials and also help explain the formation of complex organic structures observed in interstellar space. I...
A team from ORNL, Indiana University and Max Planck Institute in Germany has implemented a technique with Wollaston prisms to expand the capabilities currently available at ORNL’s High Flux Isotope Reactor instrument HB-1.
For the first time since 2011, scientific users of Oak Ridge National Laboratory’s High Flux Isotope Reactor were able to take advantage of a seventh cycle, allowing for 25 extra days of neutron production and available time for new experiments on HFIR’s 12 beam lines in fiscal ye...

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...
