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…

Time Evolution of Two-Level Systems Driven by Periodic Fields

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

In this paper we study the time evolution of a class of two-level systems driven by periodic fields in terms of new convergent perturbative expansions for the associated propagator…

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…
