Anomalous metallic phase and reduced critical current in superconducting nanowires due to inverse proximity effect
G. M. Oliveira, G. O. Steffensen, I. Casal Iglesias +7
Superconductor-to-metal transitions (SMTs) are key probes of mesoscopic superconductivity, but their interpretation can be complicated by device geometry and measurement conditions…
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…
Effective conduction-band model for zincblende III-V semiconductors in the presence of strain: tuning the properties of bulk crystals and nanostructures
Samuel D. Escribano, Alfredo Levy Yeyati, Elsa Prada
Strain provides a powerful knob to tailor the electronic properties of semiconductors. Simple yet accurate approximations that capture strain effects in demanding simulations of me…
Emergent topology by Landau level mixing in quantum Hall-superconductor nanostructures
Yuriko Baba, Alfredo Levy Yeyati, Pablo Burset
We demonstrate the emergence of novel topological phases in quantum Hall-superconductor hybrid systems driven by Landau level mixing and spin-orbit interactions. Focusing on a narr…
Fluxoid valve effect in full-shell nanowire Josephson junctions
Carlos Payá, F. J. Matute-Cañadas, A. Levy Yeyati +3
We introduce a new type of supercurrent valve based on full-shell nanowires. These hybrid wires consist of a semiconductor core fully wrapped in a thin superconductor shell and sub…
Revealing inter-band electron pairing in a superconductor with spin-orbit coupling
Javier Zaldívar, Jon Ortuzar, Miguel Alvarado +8
Most superconducting mechanisms pair electrons within the same band, forming spin singlets. However, the discovery of multi-band superconductivity has opened new scenarios for pair…
