Abstract:

A recently introduced recurrence-relation ansatz applied to the Bose-Hubbard model is here used in the generalized Aubry-André model. The resulting modified Aubry-André model allows for a simple parametrization of the solutions in terms of three parameters, viz., the system energy when the quasiperiodicity amplitude Δ = 0, the site μ where the particle is initially localized, and the tuning parameter α ∈ (−1, 1) that determines the regions of localized or extended states. The standard Aubry-André form corresponds to α = 0.
