Abstract: We analyze a generic model of mesoscopic machines driven by the nonadiabaticvariation of external parameters. We derive a formula for the probabilitycurrent; as a consequence we obtain a no-pumping theorem for cyclic processessatisfying detailed balance and demonstrate that the rectification of currentrequires broken spatial symmetry.
