Dimerized Hofstadter model in two-leg ladder quasi-crystals
Abstract We theoretically study topological features, band structure, and localization properties of a dimerized two-leg ladder with an oscillating on-site potential. The periodicity of the on-site potential can take either rational or irrational values. We consider two types of dimerized configurat...
