Topological nature of edge states for one-dimensional systems without symmetry protection

Janet Zhong, Heming Wang, Alexander N Poddubny +1

We numerically verify and analytically prove a winding number invariant that correctly predicts the number of edge states in one-dimensional, nearest-neighbor (between unit cells),…

Pole and zero edge state invariant for 1D non-Hermitian sublattice symmetry

Janet Zhong, Heming Wang, Shanhui Fan

There have been several criteria for the existence of topological edge states in 1D non-Hermitian two-band sublattice-symmetric tight-binding Hamiltonians. The generalized Brilloui…
