Magnetic texture modulated superconductivity in superconductor/ferromagnet shells of semiconductor nanowires
Nabhanila Nandi, Juan Carlos Estrada Saldaña, Alexandros Vekris +11
In a one-dimensional ferromagnet-superconductor nanowire, magnetism can suppress superconductivity except where the Zeeman field is suppressed, for example domain wall superconduct…
Phase controlled multi-terminal Josephson junction in ternary hybrid nanowire
Sabbir A. Kahn, Lukas Stampfer, Sara Marti-Sanchez +7
This work presents multiterminal Josephson junctions in hybrid semiconductor-superconductor InAsSb-Al nanocrosses. Hybrid nanocrosses are grown using molecular beam epitaxy and are…
Spin-split superconductivity in spin-orbit coupled hybrid nanowires with ferromagnetic barriers
J. Zhao, A. Mazanik, D. Razmadze +4
We report transport studies of hybrid Josephson junctions based on semiconducting InAs nanowires with fully overlapping epitaxial ferromagnetic insulator EuS and superconducting Al…
Artificial Intelligence-Assisted Workflow for Transmission Electron Microscopy: From Data Analysis Automation to Materials Knowledge Unveiling
Marc Botifoll, Ivan Pinto-Huguet, Enzo Rotunno +17
(Scanning) transmission electron microscopy ((S)TEM) has significantly advanced materials science but faces challenges in correlating precise atomic structure information with the…
Subgap transport in superconductor--semiconductor hybrid islands: Weak and strong coupling regimes
Marco Valentini, Rubén Seoane Souto, Maksim Borovkov +5
Superconductor--semiconductor hybrid systems play a crucial role in realizing nanoscale quantum devices, including hybrid qubits, Majorana bound states, and Kitaev chains. For such…
Ground state phase diagram and "parity flipping'' microwave transitions in a gate-tunable Josephson Junction
M. R. Sahu, F. J. Matute-Cañadas, M. Benito +6
We probed a gate-tunable InAs nanowire Josephson weak link by coupling it to a microwave resonator. Tracking the resonator frequency shift when the weak link is close to pinch-off,…
