Quasi-periodically driven quantum systems
(Walter De Gruyter, 2016-10-10)
Article
Open AccessFloquet theory provides rigorous foundations for the theory of periodically driven quantum systems. In the case of non-periodic driving, however, the situation is not so well understood. Here, we provide a critical review ... -
Resonance tongues and spectral gaps in quasi-periodic schrödinger operators with one or more frequencies. A numerical exploration
(2010-07)
Research report
Open AccessAbstract. In this paper we investigate numerically the spectrum of some representative examples of discrete one-dimensional Schr¨odinger operators with quasi-periodic potential in terms of a perturbative constant b and ... -
Resonance tongues in the quasi-periodic hill-Schrödinger equation with three frequencies
(2010-07)
Research report
Open AccessIn this paper we investigate numerically the following Hill’s equation x00 + (a + bq(t))x = 0 where q(t) = cos t + cosp2t + cosp3t is a quasiperiodic forcing with three rationally independent frequencies. It appears,also, as ... -
