基于延时反馈的斜搓板电位电流控制
Current control in a tilted washboard potential via time-delayed feedback
摘要：
本文研究了在静态倾斜力作用下，过阻尼布朗粒子在搓衣板势中的运动。偏置产生定向的净粒子运动，即电流。它表明，与一个额外的时间延迟的反馈项的粒子电流可以反向的偏压的方向。控制功能引起棘轮效应，其阻碍进一步的电流反转，并且因此粒子逆着静态偏置的方向移动。此外，改变延迟时间还允许在搓衣板电位中连续地降低甚至停止运输。我们确定和表征的基本机制，适用于在很宽的温度范围内的电流控制。
英文摘要：
We consider motion of an overdamped Brownian particle in a washboard potential exerted to a static tilting force. The bias yields directed net particle motion, i.e. a current. It is demonstrated that with an additional time-delayed feedback term the particle current can be reversed against the direction of the bias. The control function induces a ratchet-like effect that hinders further current reversals and thus the particle moves against the direction of the static bias. Furthermore, varying the delay time allows also to continuously depreciate and even stop the transport in the washboard potential. We identify and characterize the underlying mechanism which applies to current control in a wide temperature range.
