Scientists glimpse signs of a puzzling state of matter in a superconductor

High-temperature superconductors conduct electricity with no loss, but no one knows how they do it. SLAC scientists observed the signature of an exotic state of matter called “pair density waves” in a cuprate superconductor and confirmed that it intertwines with another exotic state.

FSU engineers improve performance of high-temperature superconductor wires

Florida State University researchers have discovered a novel way to improve the performance of electrical wires used as high-temperature superconductors (HTS). Researchers used high-resolution scanning electron microscopy to understand how processing methods influence grains in bismuth-based superconducting wires (known as Bi-2212).

Magnetism Meets Topology on a Superconductor’s Surface

Scientists have found an energy band gap—an energy range where no electrons are allowed—opens at a point where two allowed energy bands intersect on the surface of an iron-based superconductor. This unusual electronic energy structure could be used for quantum information science and electronics.

Brookhaven’s Ivan Bozovic Wins 2021 James C. McGroddy Prize for New Materials

The American Physical Society has selected physicist Ivan Bozovic of the U.S. Department of Energy’s Brookhaven National Laboratory as a co-recipient of the 2021 James C. McGroddy Prize for New Materials. Bozovic and his collaborators were recognized “For pioneering the atomic-layer-by-layer synthesis of new metastable complex-oxide materials, and the discovery of resulting novel phenomena.”

Tiny Quantum Sensors Watch Materials Transform Under Pressure

Scientists at Berkeley Lab have developed a diamond anvil sensor that could lead to a new generation of smart, designer materials, as well as the synthesis of new chemical compounds, atomically fine-tuned by pressure.
