Thermal Ratchet Effect in Confining Geometries
The stochastic model of the Feynman–Smoluchowski ratchet is proposed and solved using generalization of the Fick–Jacobs theory. The theory fully captures nonlinear response of the ratchet to the difference of heat bath temperatures. The ratchet performance is discussed using the mean velocity, the average heat flow between the two heat reservoirs and the figure of merit, which quantifies energe...
متن کاملTHERMAL RATCHET EFFECT IN FERROFLUIDS A.Engel
Introduction. The extraction of directed motion from random fluctuations is an old and controversial problem in statistical mechanics with a long and interesting history [1]. Although excluded by the second law of thermodynamics for equilibrium systems, rectification of fluctuations is possible in systems driven sufficiently far away from thermal equilibrium [2, 3]. The problem has gained renew...
متن کاملHelical polymer in cylindrical confining geometries.
Using an algorithm for simulating equilibrium configurations, we study a fluctuating helical polymer either (i) contained in a cylindrical pore or (ii) wound around a cylindrical rod. We work in the regime where both the contour length and the persistence length of the helical polymer are much larger than the diameter of the cylinder. In case (i) we calculate the free energy of confinement and ...
متن کاملEnergetics of thermal ratchet models
Several stochastic models called thermal ratchet models have been recently proposed to analyze the motor proteins such as myosin and kinesin,etc. We propose a method to study the energetics of those models, and show how the rate of energy consumption and the energy dissipation are evaluated. As a demonstration we consider ”Feynman’s ratchet”, a typical fluctuating heat engine. The motor protein...
متن کاملTransport reversal in a thermal ratchet.
Transport of a Brownian particle moving in a periodic potential is investigated in the presence of a symmetric unbiased external force. The viscous medium is alternately in contact with two heat reservoirs. We present the analytical expression of the net current at the quasi-steady-state limit. It is found that the competition of the asymmetric parameter of the potential with the temperature di...
