摘要：

We analyze the transport properties of a Brownian particle diffusing along a two-dimensional septate channel, namely, a channel formed by equal rectangular cavities separated by narrow pores, subjected to an external longitudinal drive. We determine analytical formulas for the dependence of the particle mobility and diffusivity on the geometric channel parameters at zero and large applied drives. Finally, we rule out anomalous negative mobility for pointlike particles in a septate channel. (C) 2010 Elsevier B.V. All rights reserved.
