A superconducting diode enables supercurrent to flow in only one direction, providing new
functionalities for superconducting circuits. In recent years, there has been experimental …

In noncentrosymmetric materials, the responses (for example, electrical and optical)
generally depend on the direction of the external stimuli, called nonreciprocal phenomena …

The superconducting analogue to the semiconducting diode, the Josephson diode, has long
been sought with multiple avenues to realization being proposed by theorists,–. Showing …

Cooper pairs in non-centrosymmetric superconductors can acquire finite centre-of-mass
momentum in the presence of an external magnetic field. Recent theory predicts that such …

The critical current of a superconductor can be different for opposite directions of current flow
when both time-reversal and inversion symmetry are broken. Such non-reciprocal behaviour …

Nonreciprocal transport refers to charge transfer processes that are sensitive to the bias
polarity. Until recently, nonreciprocal transport was studied only in dissipative systems …

The macroscopic coherence in superconductors supports dissipationless supercurrents that
could play a central role in emerging quantum technologies. Accomplishing unequal …

The diode effect is fundamental to electronic devices and is widely used in rectifiers and ac–
dc converters. At low temperatures, however, conventional semiconductor diodes possess a …

When both inversion and time-reversal symmetries are broken, the critical current of a
superconductor can be nonreciprocal. In this work, we show that, in certain classes of two …

A Josephson diode is a nonreciprocal circuit element that supports a larger dissipationless
supercurrent in one direction than in the other. In this Letter, we propose a class of …
