摘要翻译：
基于系统热浴方法，在此基础上，我们提出了一个新的微观模型来研究非平衡开放系统在过阻尼极限下的有向运动。利用热浴与外调制之间的耦合作为一个小扰动，在过阻尼极限下构造了具有乘性噪声和空间相关耗散的朗之万方程和相应的Fokker-Planck-Smoluchowski方程。我们考察了热力学一致性条件，并探讨了观察相感应电流的可能性，这种相感应电流是状态相关扩散的结果，而且必然是外部噪声对热浴的非线性驱动。

英文摘要：
  Based on the system heat bath approach where the bath is nonlinearly modulated by an external Gaussian random force, we propose a new microscopic model to study directed motion in the overdamped limit for a nonequilibrium open system. Making use of the coupling between the heat bath and the external modulation as a small perturbation we construct a Langevin equation with multiplicative noise and space dependent dissipation and the corresponding Fokker-Planck-Smoluchowski equation in the overdamped limit. We examine the thermodynamic consistency condition and explore the possibility of observing a phase induced current as a consequence of state dependent diffusion and, necessarily, nonlinear driving of the heat bath by the external noise.
