The usual Su-Schrieffer-Heeger model with an even number of lattice sites possesses two degenerate zero-energy modes. degeneracy the modes leads to mixing between topological left- and right-edge states, which makes it difficult implement state transfer via edge channel. Here, enlightened by Rice-Male pumping, we find that staggered periodic next-nearest-neighbor hoppings can also separate initial mixed ensures states. Significantly, construct a unique channel introducing onsite potentials...
