A Simple Thermally Driven Brownian Motor

In this work we study the directed motion (or current) of Brownianrnparticles in an inhomogeneous medium due to spatially periodicrntemperature background, and a ratchet potential with or without load.rnThe nature of the current in our model system is discussed in detail.rnIn particular we analyze the behavior of the current as a function of thernparameters specifying our model system such as temperature, barrierrnheight, trap potential, load and length of hot region
