Scatter Plot from Scientific Research

Eigenvalues of the experimental G matrix (labelled lambda ) for the four selected points in units of e 2 / h. The average diagonal element of the matrix is subtracted to centre the plot around zero for better readability. We note that the eigenvalues do not completely collapse on a single point on the real axis. This is attributed to the finite resistance of the measurement line of the grounded contact (Supplementary Section 3 ).
