Abstract

The ashing rachet is the simplest example of diusion mediated transport as well as the suggested mechanism for a class of protein motors. Here we briey explain these concepts and give an entropy based argument for existence and uniqueness of a model problem. We also examine the features of the system that lead to transport.
