Optimal modulation of a Brownian ratchet and enhanced sensitivity to a weak external force
We studied the dynamics of a Brownian particle moving in a spatially anisotropic potential acted on by multiplicative temporal modulations so that V(x,t) = g(t)U(x). Using the concept of the “thermodynamic action,” we show that the class of modulation that maximizes the flow is a square-wave in time...
