The Topological Origin of Boundary Charges at Edges of One-Dimensional Crystals without Inversion Symmetry
We report the edge states and non-zero boundary charges in one-dimensional photonic crystals (1D PhCs) without inversion symmetry. In contrast to common 1D systems, we show that edge states corresponding to non-zero boundary charges do exist in these asymmetric 1D PhCs even if we cannot obtain non-i...
