    • We use a conjugated-gradient method to minimize the KS energy in the particle-in-box representation. The Hartree potential is calculated by a Fourier convolution approach. A simplified multigrid technique is used to accelerate the convergence.

    • -4 and b = π/4. For the symmetric case γ = 0, we take λ to be 0.53, 0.6, 0.67, 0.74, and 0.81. For the asymmetric case we choose five sets of (λ,γ): (0.53, 0.1), (0.565, 0.2), (0.6, 0.1), (0.635, 0.15), and (0.67, 0.1).

    • note
    • In the time-reversal symmetric case, there are three contributions to the average IPR, the direct, exchange, and Cooper pairings. However, when using the IPR to estimate interaction effects, higher-order processes in the screened interaction may renormalize the magnitude. This is well known for the Copper channel-its final magnitude is small. We take this into account by using 2I/3 in the estimate of the interaction effect.
