16. However, we have recently found a chaotic ILM for our rotator system in the absence of driving and damping. Numerical simulations show that this mode remains localized for at least (Formula presented) librational periods, indicating that Arnold diffusion is either extremely slow or is suppressed by numerical noise. The first paper in 7 also gives an example of localized chaos in a Hamiltonian lattice, but the issue of Arnold diffusion is not discussed.
