a Measurement of dI/dVds versus Vds and B||. b Numerical calculation of state energies as a function of B||. The colour represents the calculated orbital angular momentum (blue: Lz, = −1.3 ħ, black: Lz, = 0, red: Lz, = 1.3 ħ). |g1*| and |g2*| correspond to the B-field induced splitting of the two Kramers pairs. The spin arrows indicate the alignment of the spin with respect to the nanowire axis (up/down corresponds to parallel/anti-parallel). Due to the presence of SOI, the arrows only indicate the approximate spin direction. c Calculated onsets of co-tunnelling processes starting from the lowest energy state as a function of B|| (artificial colouring). d Absolute square of the wave function (Φ) of the lowest energy state at infinitesimal B||-field and Δorb = 0. e Same as panel a, zooming in on the small anti-crossing (δ) due to coupling of states with same spin but different orbital momentum sign.
