Inter-subband coupling in multichannel Rashba nanowire Josephson junctions confines the topological phase to finite Zeeman fields, enables JDE for spin-orbit-aligned Zeeman fields, and increases diode efficiency via enhanced spectral asymmetry and Majorana bound states.
Strong correlations in a Josephson junction with odd electrons spontaneously break symmetries to enable zero-field Josephson diode effect without magnetic order.
Superconducting diodes can provide built-in nonlinearity, nonreciprocity, and quantum features to support scalable, integrated superconducting quantum circuits with improved thermal compatibility.
