Superconducting diode effect in multichannel Majorana wires
This study demonstrates that multichannel Rashba nanowires with both harmonic and rectangular confinement exhibit robust superconducting diode effects with efficiencies up to ~60%, driven by asymmetric Fulde-Ferrell states that enable high-efficiency nonreciprocal transport and allow for direct topological manipulation of Majorana zero modes via externally injected supercurrents.
