Diffusion for Hamiltonian Maps with Frequency Modulation
Abstract
The action diffusion of an area preserving map, whose linear frequency is stochastically perturbed, is described by a Fokker-Planck equation with a coefficient obtained from the normal form. The local properties are investigated on the standard map and the angle is shown to have a fast relaxation. A comparison is made with the diffusive process determined by a slow periodic modulation of the frequency.
