New Properties Discovered in Atom-Wide Troughs

BES-2016-12-e-lrg.jpg

Could adding defects make a good material better? Scientists have found that linear defects in a promising thin film create one-atom-thick metallic wires. These wires cross the otherwise intact material, offering a way to channel electrons and photons, tiny packets of light

Fast Track Control Accelerates Switching of Quantum Bits

Picture1light.png

An international collaboration between physicists at the University of Chicago, Argonne National Laboratory, McGill University, and the University of Konstanz recently demonstrated a new framework for faster control of a quantum bit. First published online Nov. 28, 2016, in Nature Physics, their experiments on a single electron in a diamond chip could create quantum devices that are less to prone to errors when operated at high speeds.

Neutrons Identify Key Ingredients of the Quantum Spin Liquid Recipe

Neutron scattering studies of a rare earth metal oxide have identified fundamental pieces to the quantum spin liquid puzzle, revealing a better understanding of how and why these materials exhibit exotic behaviors such as failing to fully freeze when exposed to sub-zero temperatures. In a paper published in Nature Physics, a team of researchers from the Georgia Institute of Technology, the University of Tennessee and the Department of Energy’s Oak Ridge National Laboratory used neutrons to examine the origins of unusual magnetic behavior in a rare earth–based metal oxide, ytterbium-magnesium-gallium-tetraoxide (YbMgGaO4). The material, discovered in 2015, is known to have strange magnetic properties, putting it in a unique category of materials classified as quantum spin liquids.

‘Spooky’ Sightings in Crystal Point to Extremely Rare Quantum Spin Liquid

ORNL.SNS.chamber.jpg

Little is rarer than an observable quantum spin liquid, but now, tests reveal that a synthetic crystal with ytterbium as its base may house one at near absolute zero. It joins an extremely short list of materials believed house myriads of particles joined together in an observable vast, shared entanglement, or "spooky action at a distance."

Exotic Insulator May Hold Clue to Key Mystery of Modern Physics

Experiments using laser light and pieces of gray material the size of fingernail clippings may offer clues to a fundamental scientific riddle: What is the relationship between the everyday world of classical physics and the hidden quantum realm that obeys entirely different rules?

Researchers Take First Look into the “Eye” of Majoranas

MF2_uninews_810.jpg

Majorana fermions are particles that could potentially be used as information units for a quantum computer. An experiment by physicists at the Swiss Nanoscience Institute and the University of Basel’s Department of Physics has confirmed their theory that Majorana fermions can be generated and measured on a superconductor at the end of wires made from single iron atoms. The researchers also succeeded in observing the wave properties of Majoranas and, therefore, in making the interior of a Majorana visible for the first time. The results were published in the Nature journal npj Quantum Information.
