We study spin transport in the one- and two-electron regimes of parallel-coupled double quantum dots (DQDs). The DQDs are formed in InAs nanowires by a combination of crystal-phase engineering and electrostatic gating, with an interdot tunnel coupling (t) tunable by one order of magnitude. Large single-particle energy separations (up to 10 meV) and |g^{*}| factors (∼10) enable detailed studies of the B-field-induced transition from a singlet-to-triplet ground state as a function of t.

Orbital Tuning of Tunnel Coupling in InAs/InP Nanowire Quantum Dots

A qualitatively different regime is observed at relatively low filling numbers, where tunneling rates are rather controlled by the axial configuration of the electron orbital, and the barrier transparency for the various orbitals is found to evolve as expected from numerical simulations.

The results reveal that the coupling of adjacent edge modes sets in at a step-to-step distance d_{ss}≤25  nm, resulting in a characteristic splitting of a single peak at the Dirac point in tunneling spectra.
