作者： wan RongZheng HU Jun fang HaiPing Division of lnterfacial Water and Laboratory of Physical Biology Shanghai Institute of Applied PhysicsChinese Academy of SciencesP.O.Box 800-204Shanghai 201800China

Based on a simple model, we theoretically show that asymmetric transportation is possible in nanoscale systems experiencing thermal noise without the presence of extemal fluctuations. The key to this theoretical advance is that the correlation lengths of the thermal fluctuations become significantly long for nanoscale systems. This differs from macroscopic systems in which the thermal noises are usually treated as white noise. Our observation does not violate the second law of thermodynamics, since at the nanoscale, extra energy is required to keep the asymmetric structure against thermal fluctuations.
