-breaking threshold in spatially asymmetric Aubry-Andre Harper models: hidden symmetry and topological states

Andrew K. Harter, Tony E. Lee, Yogesh N. Joglekar

Aubry-Andre Harper (AAH) lattice models, characterized by reflection-asymmetric, sinusoidally varying nearest-neighbor tunneling profile, are well-known for their topological prope…
