摘要翻译:
我们考虑了热平衡驱动下的过阻尼扩散过程,并分析了它们的动力学定常涨落。讨论了占位时间和电流联合涨落的热力学解释;它们分别包含了涨落的时间对称扇区和时间反对称扇区。我们强调了联合涨落的正则结构。交通量的新概念补充了熵产生法对占用统计的研究。我们解释了占位和电流波动是如何在平衡状态下相互耦合的。它们的解耦接近平衡解释了熵产生原理的有效性。

英文摘要:
We consider overdamped diffusion processes driven out of thermal equilibrium and we analyze their dynamical steady fluctuations. We discuss the thermodynamic interpretation of the joint fluctuations of occupation times and currents; they incorporate respectively the time-symmetric and the time-antisymmetric sector of the fluctuations. We highlight the canonical structure of the joint fluctuations. The novel concept of traffic complements the entropy production for the study of the occupation statistics. We explain how the occupation and current fluctuations get mutually coupled out of equilibrium. Their decoupling close-to-equilibrium explains the validity of entropy production principles.
