Bulk-edge correspondence for the nonlinear eigenvalues problem of the Haldane model
Bulk-edge correspondence for the nonlinear eigenvalues problem of the Haldane model
Recently, there is an interest in studying the bulk-edge correspondence for nonlinear eigenvalue problems in a two-dimensional topological system with spin-orbit coupling. By employing the method of the auxiliary eigenvalues as introduced in T. Isobe et al., Phys. Rev. Lett. 132, 126601 (2024), the nonlinear bulk-edge correspondence was established. In …
