Signatures of time-reversal-symmetry breaking in multiband 2H-TaS2 revealed by zero-field Josephson nonreciprocity
Daniel Margineda, David Caldevilla-Asenjo, Yuriy Yerin +7
Superconductors that spontaneously break time-reversal symmetry host complex order parameters and are widely regarded as a hallmark of unconventional superconductivity. Whether suc…

Degenerate monolayer Ising superconductors via chiral-achiral molecule intercalation
Daniel Margineda, Covadonga Ãlvarez-GarcÃa, Daniel Tezze +8
Engineering unconventional superconductors is a central challenge in condensed matter physics. Molecule-intercalated TaS2 superlattices have recently been reported to host such sta…

Coherent subgap transport in spin-split Josephson junctions
David Caldevilla-Asenjo, Gorm Ole Steffensen, Sara Catalano +6
We report the first experimental observation of subgap transport in ferromagnetic insulator/superconductor/insulator/superconductor junctions realized in EuS/Al/AlOx/Al vertical st…
