Topology of the generalized Brillouin zone of one-dimensional models
Heming Wang, Janet Zhong, Shanhui Fan
The generalized Brillouin zones (GBZs) are integral in the analysis of non-Hermitian band structures. Conventional wisdom suggests that the GBZ should be connected, where each poin…
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…
