Two possible spiral states as a function of Dzyaloshinskii–Moriya (DM) interaction. a The potential barrier that is calculated from \(E_{{\mathrm{barrier}}}^{{\mathrm{norm}}} = E_{{\mathrm{ani}}}^{{\mathrm{S, norm}}} - E_{{\mathrm{ani}}}^{{\mathrm{AS, norm}}}\) in the range of DM energy. Note that when dy/dc » 2, so that the soliton is well-described by the pure spiral configuration lz = cos(kz), \(E_{{\mathrm{barrier}}}^{{\mathrm{norm}}}\) is described as a cardinal sine or sinc function Γnorm, implying that \(E_{{\mathrm{barrier}}}^{{\mathrm{norm}}}\) is negligible with large DM interaction or the long length lw. b The normalized anisotropy energies, \(E_{{\mathrm{ani}}}^{{\mathrm{S, norm}}}\) (symmetric state, S state) and \(E_{{\mathrm{ani}}}^{{\mathrm{AS, norm}}}\) (antisymmetric state, AS state)
