Stability for quasi-periodically perturbed Hill's equations

Guido Gentile, Daniel A. Cortez, Joao C. A. Barata

We consider a perturbed Hill's equation of the form $ϕ ¨ + (p_{0} (t) + ε p_{1} (t)) ϕ = 0$ , where $p_{0}$ is real analytic and periodic, $p_{1}$ is real analytic and quasi-periodic…

Perturbative Analysis of Dynamical Localisation

J. C. A. Barata, D. A. Cortez

In this paper we extend previous results on convergent perturbative solutions of the Schroedinger equation of a class of periodically time-dependent two-level systems. The situatio…
