    Abstract

    Noninertial transport of classical objects driven through periodically modulated potential-energy landscapes by constant, uniform forces was discussed. The one-dimensional varient of this problem were throughly investigated, and its result were applied profitably to processes such as gel electrophoresis. It was observed that objects driven through periodically modulated potential-energy landscapes in two dimensions can become locked in to symmetry-selected directions that are independent of the driving force's orientation. It was suggested that periodic potential-energy landscapes have exceptional promise for sorting continuous streams of mesoscopic objects.
