Controlling chaotic transport in a Hamiltonian model of interest to magnetized plasmas

International audienceWe present a technique to control chaos in Hamiltonian systems which are close to integrable.By adding a small and simple control term to the perturbation, the system becomes more regular than the original one. We apply this technique to a model that reproduces turbulent ExB drift and show numerically that the control is able to drastically reduce chaotic transport
