24. In our experiment, maximum negative drag did not increase dramatically with increasing magnetic field above 3 T. This indicates that there is no transition at higher magnetic field, so we assume the Wigner crystal state as the extreme of strongly correlated state.
25. drive is below the plateau and the driving current is not completely proportional to the bias voltage along the drive wire. This nonlinearity, i.e., current suppression at low bias voltage, indicates the charge accumulation toward the drain (27). The negative drag is generated by a nonlinear, hydrodynamic effect and that Onsager's relations are specifically invalid in this context.
