Figure 2 | Localized Hinge States in the YMM Cylinder under Different Models. (a) Dispersion spectra for a circular YMM cylinder calculated using FEMs. (b) Energy density distributions for four HOTI-type hinge-localized states, marked by circles in panel (a). (c-f) Similar to (a-b) but calculated using: (c-d) a 1D plane wave expansion of the varying global surface Weyl Hamiltonian HGS, and (e-f) four local Weyl Hamiltonians HLS coupled with an effective magnetic field. The orange lines in (e) indicate the chiral zero modes, while the purple and gray regions represent the bulk band region of the YMM and air, respectively.
