Topologically nontrivial states in one-dimensional nonlinear bichromatic superlattices

C. S. Liu, Z. Z. Wang. Chuanhao Yin, Y. D. Wu +3

We study topological properties of one-dimensional nonlinear bichromatic superlattices and unveil the effect of nonlinearity on topological states. We find the existence of nontriv…
