3 problems

Consider an edge direction for which the no-fold condition fails. In this setting, the edge problem may exhibit long-lived resonant states rather than genuine eigenvalue edge state…

Let ${\mathscr{P}}_\delta[\zeta]:H^2[\zeta]\to L^2[\zeta]$ be the family of edge operators, with Dirac points $(\xi_\star^A,E_\star)$ and $(\xi_\star^B,E_\star)$ satisfying…

Consider the edge-state eigenvalue problem for $H^{(\varepsilon,\delta)}$ in Case (2), where $\varepsilon V_{1,1}<0$ and the small-parameter condition eref{small-eps-delta} holds.…
