    • In Sec. III, the DW’s are labeled by l or m indicating the distance between the two DW’s in the unit of three spins. However, we here label the position of the DW as the site index in order to calculate the dispersion curve along the chain

    • z = 1/3 DW dispersion curve as (Formula presented). However, the qualitative feature of the dispersion curve near the bottom (k = π/3) is not changed by the second-order perturbation, since the coefficient of cos 6k term is negative

    • We have assumed N = even, so that the double-Néel order (↑↑↓↓) is realized at zero magnetic field with no defect. If we use N = odd, the roles of the M = even step and M = odd step are exchanged
