Description

I will consider the thermodynamic properties of an information engine that uses feedback control to extract work from a manipulated stochastic system. I will discuss the fluctuation theorems that involve the information associated with the feedback-controlled stochastic trajectories. Such an information turns out to be based on the first-passage-time distribution. I will then discuss the experimental verification of the above results with a setup consisting of a cantilever submitted to an electrostatic feedback force. I will finally show that the fluctuation theorems extend beyond the specific application to such an experiment.
