The so-called superconducting (SC) diode effect is an interesting nonreciprocal phenomenon, occurring when a material is SC in one direction and resistive in the other. This effect has been the focus ...

Atomic-scale mechanical motions in nanowires can be excited by high-frequency alternating superconducting Josephson currents. In niobium dimer nanowires three vibrational modes were experimentally ...

An experimental discovery of a fundamental physical phenomenon is not something that happens often. Yet this is what Skoltech researchers and their European colleagues recently managed to do: In their ...

Josephson junctions are quantum mechanical devices consisting of two superconductors separated by a thin insulating barrier. They are named after Brian Josephson, who predicted their unique properties ...

Using ultracold atoms and laser light, researchers recreated the behavior of a Josephson junction—an essential component of quantum computers and voltage standards. The appearance of Shapiro steps in ...
