WebbWe here propose and develop a theory for an enhancement mechanism of the diode effect arising from spontaneous symmetry breaking. We show - both within a phenomenological and a microscopic theory - that there is a coupling of the supercurrent and the underlying symmetry-breaking order parameter. WebbFollowing that, a plethora of nonreciprocal QMJJ and other architectures have been investigated and future directions for optimizations and novel explorations will be. discussed, as well as the broader impact of QMJJs, will be discussed.

The … Webb20 jan. 2024 · We clarify the temperature scaling of the nonreciprocal depairing current near the critical temperature and point out its significant enhancement at low temperatures. It is also found that the nonreciprocal critical current shows sign reversals upon increasing the magnetic field.
