论文摘要
我们研究了由高斯白噪声驱动的倾斜的粗糙电势中过度阻尼的布朗颗粒的运输。我们将各种形式的粗糙电位分析，以分析粗糙度对产生的扩散和电流的影响。电流，扩散系数的变化，以及与静态倾斜力，粗糙度和温度振幅相关的peclet数量。我们得出的结论是，粗糙度可在任何温度范围内降低粒子电流。但是在低温下，它增强了粒子的扩散系数
We study the transport of an overdamped Brownian particle in a tilted rough potential driven by a gaussian white noise.We conisder various forms of rough potentials to analyse the effect of roughness on the diffusion and current generated.The variation of current, diffusion coefficient, and peclet number with the static tilting force, amplitude of roughness and temperature were studied. We concluded that the roughness reduces the particle current at any range of temperature. But at low temperatures, it enhances the diffusion coeffeicient of the particle
