论文摘要
非平衡系统中热波动的特征函数的特征是大偏差函数，其对称性产生了波动定理。在平衡中，较大的偏差函数消失，热波动是有界的。在这里，我们考虑了平衡中热波动的特征功能，构成了对大偏差行为的子领先校正。通过振荡器与显式多振荡器热库进行建模系统，我们评估了特征功能。
The characteristic function for heat fluctuations in a non equilibrium system is characterised by a large deviation function whose symmetry gives rise to a fluctuation theorem. In equilibrium the large deviation function vanishes and the heat fluctuations are bounded. Here we consider the characteristic function for heat fluctuations in equilibrium, constituting a sub-leading correction to the large deviation behaviour. Modelling the system by an oscillator coupled to an explicit multi-oscillator heat reservoir we evaluate the characteristic function.
