Efficiency, coherent transport and entropy fluctuations in a Brownian motor driven by time-dependent temperature

We investigate the transport and energetics of a Brownian motor driven by position dependent temperature. We found that coupling enhances the current as well as the efficiency. Novel features such as current reversal with respect to the coupling strenth and inertia of the Brownian particle is also observed. We also find that the total entropy production satisfies the fluctuation theorem in the steady state.
