Effect of thermal noise on noncontact rack and pinion device.
We study a nanoscale system composed of one corrugated plate (rack) and one corrugated cylinder (pinion) coupled via the lateral Casimir force. We assume that the rack moves uniformly. The axle of the pinion experiences frictional torque and random torque due to a surrounding fluid. We show that even in the presence of thermal noise, the device can work against external loads: The pinion rotates with a nonzero average velocity. The device operation becomes less influenced by the noise as the gap between rack and pinion decreases.
