Abstract
A Brownian information engine can induce directed motion of a Brownian particle in a single heat bath at constant temperature by extracting work from the information about the microscopic state of the particle, and serves as a model for artificial and biological submicron scale engines. Much of the experimental studies to date are limited to the realization of an information engine where the initial state of the system is in thermal equilibrium; however, most of the biological and artificial motors operate far from equilibrium. Here, we realize a cyclic information engine operating in a nonequilibrium steady state consisting of a Brownian particle in an optical trap and investigate the optimal operating conditions for maximum work, power, and efficiency. The performance of our information engine depends on the cycle period τ and the distance xf that the trap center is shifted with respect to the reference distance xm. We found that the extracted work increases with increasing τ and is maximum when τ reaches infinity and xf2xm, while the extracted power is maximum at finite τ for xf ≥xm and when τ approaches zero for xf
