High-temperature superconductors, with a twist?

Fabrication method could facilitate materials discovery

20-Dec-2023 - Superconductors have intrigued physicists for decades. But these materials, which allow the perfect, lossless flow of electrons, usually only exhibit this quantum-mechanical peculiarity at temperatures so low – a few degrees above absolute zero – as to render them impractical. A research team led ...

Pairing of electrons in artificial atoms discovered

18-Aug-2023 - Researchers from the Department of Physics at Universität Hamburg, observed a quantum state that was theoretically predicted more than 50 years ago by Japanese theoreticians but so far eluded detection. By tailoring an artificial atom on the surface of a superconductor, the researchers succeeded ...
