论文摘要
与破裂的时间反向对称性相关的熵产生速率为从驱动的胶体颗粒到分子电机的平衡提供了纳米系统的基本表征。通常期望对动态状态的访问有限,从而阻碍了可观察到的可观察到的正确估计。在这里,我们展示了如何精确地保留其平稳性的平均值和波动的无内存跳跃过程。这支持了波动定理的单次适用性用于熵,并允许推断真正的热力学以及无法访问的过程详细信息。
The entropy production rate associated with broken time-reversal symmetry provides an essential characterization of nanosystems out of equilibrium, from driven colloidal particles to molecular motors. Limited access to the dynamical states is generally expected to hinder the correct estimation of this observable. Here we show how memoryless jump processes can be coarse grained exactly preserving its average and fluctuations at stationarity. This supports univocal applicability of fluctuation theorems for entropy and allows inference of the genuine thermodynamics together with inaccessible process details.
