Gate-tunable polarity inversions and three-fold rotation symmetry of the superconducting diode effect
William F. Schiela, Melissa Mikalsen, Daniel Crawford +4
The superconducting diode effect is an asymmetry in the critical current with respect to the supercurrent polarity. One impetus driving recent interest in the effect is its depende…

Josephson anomalous vortices
Dan Crawford, Stefan Ilić, Pauli Virtanen +1
We show that vortices with circulating current, related with odd-frequency triplet pairing, appear in Josephson junctions where the barrier is a weak ferromagnet with strong spin-o…

Superconducting diode effect in diffusive superconductors and Josephson junctions with Rashba spin-orbit coupling
Stefan Ilic, Pauli Virtanen, Daniel Crawford +2
We characterize the superconducting diode effect (SDE) in two-dimensional diffusive structures with Rashba spin-orbit coupling using the quasiclassical formalism. We consider both…
