24. Here we expected that the effect of spin selectivity of the edge states in the ejection phase is small. This would be caused by the charge redistribution in the edge states (Ref.), which makes the interedge distance above the Fermi level shorter than the distance below the level. In the measurement with square wave excitation, the state in the SLQD is shifted far above the Fermi level on the order of meV in the ejection phase. Then the interedge distance is small and the spin selectivity will be negligible.
25. out might be different. These values will be evaluated by using real-time measurement of the tunneling events (Ref.).
26. First, we evaluated using Eq. . The unknown parameter A was obtained assumed to have no magnetic field dependence.
27. xx around 1.55 T is a fake peak caused by an imperfect Ohmic contact.
