Anomalous diffusion in quantum Brownian motion with colored noise
- Department of Physics, University of Michigan, Ann Arbor, Michigan 48109-1120 (United States)
Anomalous diffusion is discussed in the context of quantum Brownian motion with colored noise. It is shown that earlier results follow simply and directly from the fluctuation-dissipation theorem. The limits on the long-time dependence of anomalous diffusion are shown to be a consequence of the second law of thermodynamics. The special case of an electron interacting with the radiation field is discussed in detail. We apply our results to wave-packet spreading.
