  text: The spin-orbit interaction permits to control the state of a spin qubit via
    electric fields. For holes it is particularly strong, allowing for fast all electrical
    qubit manipulation, and yet an in-depth understanding of this interaction in hole
    systems is missing. Here we investigate, experimentally and theoretically, the
    effect of the cubic Rashba spin-orbit interaction on the mixing of the spin states
    by studying singlet-triplet oscillations in a planar Ge hole double quantum dot.
    Landau-Zener sweeps at different magnetic field directions allow us to disentangle
    the effects of the spin-orbit induced spin-flip term from those caused by strongly
    site-dependent and anisotropic quantum dot g tensors. Our work, therefore, provides
    new insights into the hole spin-orbit interaction, necessary for optimizing future
    qubit experiments.
