For three decades, one quiet crystal has sat at the center of a fierce argument about how exotic superconductors really work.

In their quest to explore and characterize high-temperature superconductors, physicists have mostly focused on a material that is not the absolute highest. That's because that crystal is much easier ...

Experiments show Josephson junction-like behavior can arise with only one superconductor, challenging the standard two-superconductor model. (Nanowerk News) Separate two superconductors with a thin ...
