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.

A vision-transformer neural network trained unsupervised on synthetic conductance data proposes Hamiltonian parameter updates that drive quantum dot chains into the topological phase with Majorana modes, often succeeding in a single step.
Z2-protected Majorana vortex end modes appear in time-reversal invariant higher-order topological insulators and in topologically trivial insulators with all surfaces gapped when chemical potential lies between the two single-TI critical values.
Precessing magnetization in ballistic S/F/S junctions produces long-range spin-polarized triplet correlations, switching the junction from off to on state with finite Josephson current in fully polarized ferromagnets.
Sr2RuO4 exhibits reversed anisotropy in Andreev bound states, pointing to inter-orbital superconducting pairing that generates surface states while suppressing edge modes.
Analytical expressions for Majorana bound states in skyrmion-vortex pairs demonstrate that spin-orbit coupling is essential for their stabilization, with results matching numerical simulations.
