Illustrations of BZ of MX. (a) Without the SOC inclusion, six DNLs surround the K point in the

plane and two sixfold degenerate nodal points (sixfold DNPs) locate at the Γ–A path of the BZ. (b) With the SOC inclusion, each DNL surrounding the k point will be broken into WPs with the opposite chirality, as marked by WP+ and WP-. The sixfold DNPs will be broken into two TDNPs still on the Γ–A path.
