摘要：
The effect of external noise on diffusion processes in a Hamiltonian system with an external force is studied. This is represented by the standard map with an external force. When external noise is applied to the system, we find strongly enhanced diffusion in a parameter range in which anomalous diffusion occurs. Although chaotic orbits are not deterministic in a strict sense, because the system includes noises, they exhibit Levy flight due to the intermittent sticking to transient tori.
