  bibo_abstract:
  - 'In this note, we consider the dynamics associated to a perturbation of an integrable
    Hamiltonian system in action-angle coordinates in any number of degrees of freedom
    and we prove the following result of ``micro-diffusion'''': under generic assumptions
    on $ h$ and $ f$, there exists an orbit of the system for which the drift of its
    action variables is at least of order $ \sqrt {\varepsilon }$, after a time of
    order $ \sqrt {\varepsilon }^{-1}$. The assumptions, which are essentially minimal,
    are that there exists a resonant point for $ h$ and that the corresponding averaged
    perturbation is non-constant. The conclusions, although very weak when compared
    to usual instability phenomena, are also essentially optimal within this setting.@eng'
