Query: Topological weak mixing and diffusion at all times for a class of
  Hamiltonian systems   We present examples of nearly integrable analytic Hamiltonian systems with
several strong diffusion properties: topological weak mixing and diffusion at
all times. These examples are obtained by AbC constructions with several
frequencies.
