Transport Signatures of Radial Rashba Spin-Orbit Coupling at Ferromagnet/Superconductor Interfaces
Andreas Costa, Jaroslav Fabian
Spin-orbit coupling (SOC) emerging at the interfaces of superconducting magnetic tunnel junctions is at the heart of multiple unprecedented physical phenomena, covering triplet pro…
Unconventional Josephson supercurrent diode effect induced by chiral spin-orbit coupling
Andreas Costa, Osamu Kanehira, Hiroaki Matsueda +1
Chiral materials lacking mirror symmetry can exhibit unconventional spin-orbit fields, including fully momentum-aligned radial Rashba fields as seen in twisted van der Waals homobi…
Link between supercurrent diode and anomalous Josephson effect revealed by gate-controlled interferometry
Simon Reinhardt, Tim Ascherl, Andreas Costa +9
In Josephson diodes the asymmetry between positive and negative current branch of the current-phase relation leads to a polarity-dependent critical current and Josephson inductance…
Phenomenological Theory of the Supercurrent Diode Effect: The Lifshitz Invariant
Denis Kochan, Andreas Costa, Iaroslav Zhumagulov +1
Nonreciprocal phenomena in the normal state are well established and key to many commercial applications. In contrast, superconducting analogs, such as the superconducting diode ef…
Microscopic study of the Josephson supercurrent diode effect in Josephson junctions based on two-dimensional electron gas
Andreas Costa, Jaroslav Fabian, Denis Kochan
Superconducting systems that simultaneously lack space-inversion and time-reversal symmetries have recently been the subject of a flurry of experimental and theoretical research ac…
Sign reversal of the AC and DC supercurrent diode effect and 0--like transitions in ballistic Josephson junctions
Andreas Costa, Christian Baumgartner, Simon Reinhardt +9
The recent discovery of intrinsic supercurrent diode effect, and its prompt observation in a rich variety of systems, has shown that nonreciprocal supercurrents naturally emerge wh…
