Brownian particles confined in a two-dimensional enclosure that give rise to a bistable entropic potential are considered. With the introduction of an intermediate lobe, the mean first passage time from one lobe to another through the intermediate shows a turnover behavior with the variation of the stability of the entropic intermediate. The mean escape time shows a minimum for an optimal value of the barrier height of the intermediate state. A three-state model is proposed to explain the nonmonotonic behavior of the entropic transport.
研究了限制在二维封闭空间中产生双稳熵势的布朗粒子。通过引入一个中间叶，从一个叶通过中间叶到另一个叶的平均首次通过时间随着熵中间态稳定性的变化呈现出翻转行为。平均逃逸时间在中间态势垒高度的最佳值处出现最小值。提出了一个三态模型来解释熵输运的非单调行为。
