Externally driven molecular ratchets on a periodic potential surface: a rate equations approach

Abstract

The long time dynamics of molecular ratchets on a 1D periodic potential energy surface (PES) subjected to an external stimulus is studied using the rate equation method.

Conversion of heat to work: An efficient inchworm

“…An inchworm model for ratcheting is considered in the literature under varied circumstances [5][6][7][8][9][10][11][12]. It has already been shown that an inversion symmetry broken inchworm when immersed in a heat bath can show directed motion because of differential response at the two ends under uniform driving by the equilibrium fluctuations of the bath [13].…”
