Phys. Rev. Lett. 88, 190601 (2002) [4 pages]Brownian Motion Exhibiting Absolute Negative MobilityReceived 18 September 2001; published 26 April 2002 We consider a single Brownian particle in a spatially symmetric, periodic system far from thermal equilibrium. This setup can be readily realized experimentally. Upon application of an external static force F, the average particle velocity is negative for F>0 and positive for F<0 (absolute negative mobility). © 2002 The American Physical Society URL:
