论文摘要
我们提出了一种方法，以近似于布朗运动的熵产生，具有倾斜的周期性潜力。近似源于众所周知的热力学不确定性关系。通过应用病毒样膨胀，我们仅在漂移速度和扩散方面提供了更严格的下限。在紧密结合方案中，系统地分析了所提出的方法。我们还提供了一个相对简单的规则，可以使用基于漂移和扩散关系而不是能量障碍和力的紧密结合方法来验证。我们还讨论了在紧密结合制度之外的结果的含义。
We presented a methodology to approximate the entropy production for Brownian motion in a tilted periodic potential. The approximation stems from the well known thermodynamic uncertainty relation. By applying a virial-like expansion, we provided a tighter lower limit solely in terms of the drift velocity and diffusion. The approach presented is systematically analysed in the tight-binding regime. We also provide a relatively simple rule to validate using the tight-binding approach based on drift and diffusion relations rather than energy barriers and forces. We also discuss the implications of our results outside the tight-binding regime.
