摘要翻译:
在[L.Machura,M.Kostur,P.Talkner,J.Luczka和P.Hanggi,Phys.Rev.Lett.98,040601(2007)]的基础上,我们将惯性布朗马达的研究扩展到非对称势的情形。发现在非对称势的存在下会出现一些输运现象。在参数化的条件下,存在两个载荷最优值,即平均速度最大时载荷最优值,即在两个参数化条件下,一个载荷可以促进运输。另外,当负载增加时,可以观察到多次电流反向的现象。

英文摘要:
Based on recent work [L. Machura, M. Kostur, P. Talkner, J. Luczka, and P. Hanggi, Phys. Rev. Lett. 98, 040601 (2007)], we extend the study of inertial Brownian motors to the case of an asymmetric potential. It is found that some transport phenomena appear in the presence of an asymmetric potential. Within tailored parameter regimes, there exists two optimal values of the load at which the mean velocity takes its maximum, which means that a load can facilitate the transport in the two parameter regimes. In addition, the phenomenon of multiple current reversals can be observed when the load is increased.
