Molecular motor efficiency is maximized in the presence of both power-stroke and rectification through feedback

Molecular motor efficiency is maximized in the presence of both power-stroke and rectification through feedback

We present a model for a feedback-controlled ratchet consisting of a Brownian particle and a moving, finite barrier that is shifted by an external agent depending on the position of the particle. By modifying the value of a single parameter of the feedback protocol, the model can act either as a pur...
