摘要：
The efficiency of different types of Brownian motors is calculated analytically and numerically. We find that motors based on flashing ratchets present a,low efficiency and an unavoidable entropy production. On the other hand, a certain class of motors based on adiabatically changing potentials, named reversible ratchets, exhibit a higher efficiency and the entropy production can be arbitrarily reduced.
