The optimal driving waveform for overdamped, adiabatic rocking ratchets

چکیده
The optimal driving waveform among a wide class of admissible functions for an overdamped, adiabatic rocking ratchet is shown to be dichotomous. ‘Optimum’ is defined as that which achieves the maximum (or minimum negative) average particle velocity. Implications for the design of ratchets, for example in nanotechnological transport, may follow. The main result is applicable to a general class of adiabatic responses. Much scope exists for further studies of ratchet waveform optimization in other regimes. PACS numbers: 05.60.Cd, 02.30.−f

Optimal driving waveform for overdamped, adiabatic rocking ratchets
As a first step in the project of ratchet optimisation, the optimal driving waveform among a wide class of admissible functions for an overdamped, adiabatic rocking ratchet is shown to be dichotomous. ‘Optimum’ is defined as that which achieves the maximum (or minimum negative) average particle velocity. Implications for the design of ratchets, for example in nanotechnological transport, may fo...
متن کاملOverdamped Deterministic Ratchets Driven by Multifrequency Forces∗
We investigate a dissipative, deterministic ratchet model in the overdamped regime driven by a rectangular force. Extensive numerical calculations are presented in a diagram depicting the drift velocity as a function of a wide range of the driving parameter values. We also present some theoretical considerations which explain some features of the mentioned diagram. In particular, we proof the e...
متن کاملDeterministic transport in ratchets.
We present the deterministic transport properties of driven overdamped particles in a simple piecewise-linear ratchet potential. We consider the effects on the stationary current due to local spatial asymmetry, time asymmetry in the driving force, and we include the possibility of a global spatial asymmetry. We present an extremely simple scheme for evaluating the current that is established on...
متن کاملGiant coherence in driven systems
We study the noise-induced currents and reliability or coherence of transport in two different classes of rocking ratchets. For this, we consider the motion of Brownian particles in the over damped limit in both adiabatic and non-adiabatic regimes subjected to unbiased temporally symmetric and asymmetric periodic driving force. In the case of a time asymmetric driving, we find that even in the ...
متن کاملGiant enhancement of diffusion and particle selection in rocked periodic potentials
– We investigate the motion of an overdamped Brownian particle in a periodic potential with weak thermal noise and a time-periodic unbiased (i.e. 〈F (t)〉 = 0) external driving force F (t). By introducing appropriate “waiting-periods”, where F (t) vanishes, an arbitrarily strong enhancement of diffusion in a symmetric potential is possible. In asymmetric periodic potentials (ratchets) the net fl...
