From: Topological kink plasmons on magnetic-domain boundaries
Dispersion of kink magnetoplasmons (KMPs) with large angular wavenumber. The dispersion for \({B}_{0}=0.1\) T, \(\Delta B_{\mathrm{m}}=0.15\) T, \(\bar{B}_{\mathrm{m}}=0\) T, and \({n}_{0}=1\times 1{0}^{11}\ {{\rm{cm}}}^{-2}\) with large range of angular wavenumber \(|m|\) up to 80. The quasi-odd modes first go up and then go down
