The so-called superconducting (SC) diode effect has recently attracted significant attention within the physics research community, due to its potential value for developing new technologies. This effect provides a key example of nonreciprocal superconductivity, as materials hosting it are essentially superconducting in one current flow direction and resistive in the other.
