Localization–delocalization transition in the Generalized Aubry–André–Harper model in a quasiperiodic superlattice potential

We investigate localization–delocalization transition in the one-dimensional generalized Aubry–André–Harper (GAAH) model in a quasiperiodic superlattice potential. The critical interplay between the model's two modulated energy scales — the hopping amplitude (t) and the on-site potential (Δ) —...
