两耦合布朗粒子的流和整流效率研究

Study on the Current and the Efficiency of the Coupled Brownian Motor

本文根据Suzuki and Munakata的新的效率定义,研究了两耦合布朗马达在非对称周期性闪烁棘轮和摇摆棘轮中的整流效率.这里,力是非对称的无偏外力,闪烁是无偏非对称的闪烁,模拟了复杂外界环境下分子马达的运动,根据结果可以看出传统效率定义中效率随流的线性变化关系在新效率定义下发生了变化,同时通过闪烁棘轮和摇摆棘轮单一分子马达与两耦合布朗马达的流和效率曲线,讨论了非对称参数对有结构分子马达定向输运的影响.

In this article, following the definition of efficiency by Suzuki and Munakata, we discussed two coupled Brownian motors＇rectifying efficiency. In this text, the force is dissymmetrical unbiased, also the flashing ratchet, we simulated motors move in complicated external condition. Bases on the results, we can see some changes between the definition of the conventional and the newest efficiency. At the same time bases on the curves of currents and efficiencies in flashing and rocking ratchet of one particle and two coupled motors, we discussed the effect of non - monotonous function in configurable particles directional moving.
