对“一维过阻尼系统中的绝对负迁移率”一文的评论
Comment on 'Absolute negative mobility in a one-dimensional overdamped system'
摘要：
最近Ru-Yin Chen等人（Phys. Lett. A 379（2015）2169-2173）给出了关于一维过阻尼系统中的绝对负迁移率（ANM）的结果，并声称提出了ANM的新的极小模型。我们认为作者在计算中引入了一个错误。然后我们对相应的朗之万方程进行了精确的数值模拟，结果表明在所考虑的系统中没有发生ANM现象。
英文摘要：
Recently Ru-Yin Chen et al. (Phys. Lett. A 379 (2015) 2169-2173) presented results on the absolute negative mobility (ANM) in a one-dimensional overdamped system and claimed that a new minimal model of ANM was proposed. We suggest that the authors introduced a mistake in their calculations. Then we perform a precise numerical simulation of the corresponding Langevin equation to show that the ANM phenomenon does not occur in the considered system.
