Abstract
In this work we study the directed motion (or current) of Brownian
particles in an inhomogeneous medium due to spatially periodic
temperature background, and a ratchet potential with or without load.
The nature of the current in our model system is discussed in detail.
In particular we analyze the behavior of the current as a function of the
parameters specifying our model system such as temperature, barrier
height, trap potential, load and length of hot region
