Josephson Effect in Unconventional Superconductors

In this letter we present a simple relation, that allows one to predict the Josephson current between two unconventional superconductors with arbitrary band-structure and pairing symmetry. We illustrate this relation with examples of s-wave and d-wave junctions and show a detailed numerical comparison with the phenomenological Sigrist and Rice relation [1] commonly used to interpret tunneling e...

Josephson Effect between Conventional and Rashba Superconductors

We study the Josephson effect between a conventional s-wave superconductor and a non-centrosymmetric superconductor with Rashba spin-orbit coupling. Rashba spin-orbit coupling affects the Josephson pair tunneling in a characteristic way. The Josephson coupling can be decomposed into two parts, a ‘spin-singlet-like’ and a ‘spin-triplet-like’ component. The latter component can lead to shift of t...

Fate of the Josephson effect in thin-film superconductors

The dc Josephson effect refers to the dissipationless electrical current – the supercurrent – that can be sustained across a weak link connecting two bulk superconductors.1 This effect is a probe of the fundamental nature of the superconducting state, which depends crucially on the spatial dimensionality of the superconducting electrodes. For bulk (i.e. threedimensional) superconductors, the su...

Anomalous Josephson effect between even- and odd-frequency superconductors.

We demonstrate that, contrary to standard wisdom, the lowest-order Josephson coupling is possible between odd- and even-frequency superconductors. The origin of this effect is the induced odd- (even-)frequency pairing component at the interface of bulk even- (odd-)frequency superconductors. The resulting current-phase relation is found to be proportional to cosphi, where phi is the macroscopic ...

Kondo effect and Josephson current through a quantum dot between two superconductors

We investigate the supercurrent through a quantum dot for the whole range of couplings using the numerical renormalization group method. We find that the Josephson current switches abruptly from a pto a 0-phase as the coupling increases. At intermediate couplings the total spin in the ground state depends on the phase difference between the two superconductors. Our numerical results can explain...
