## Description

- description: We report on an experimental study of spin and valley blockade in two-electron
    bilayer graphene (BLG) double quantum dots (DQDs) and explore the limits set by
    asymmetric orbitals and electron- electron interactions. The results obtained
    from magnetotransport measurements on two-electron BLG DQDs, where the resonant
    tunneling transport involves both orbital symmetric and antisymmetric two-particle
    states, show a rich level spectrum. We observe a magnetic field tunable spin and
    valley blockade, which is limited by the orbital splitting, the strength of the
    electron-electron interaction and the difference in the valley g-factors between
    the symmetric and antisymmetric two- particle orbital states. Our conclusions
    are supported by simulations based on rate equations, which allow the identification
    of prominent interdot transitions associated with the transition from single to
    two-particle states observed in the experiment.
