We find the moment generating function (mgf) of the nonequilibrium work for open systems undergoing a thermal process, i.e., when the stochastic dynamics maps thermal states into time-dependent thermal states. The mgf is given in terms of a temperaturelike scalar satisfying a first-order ordinary differential equation. We apply the result to some paradigmatic situations: a levitated nanoparticle in a breathing optical trap, a Brownian particle in a box with a moving piston, and a two-state system driven by an external field, where the work mgfs are obtained for different timescales and compared with Monte Carlo simulations.
我们找到了经历热过程的开放系统非平衡功的矩生成函数（mgf），即当随机动力学将热态映射为随时间变化的热态时的情况。该mgf是根据一个满足一阶常微分方程的类似温度的标量给出的。我们将该结果应用于一些典型情况：处于呼吸光学阱中的悬浮纳米颗粒、具有移动活塞的盒子中的布朗粒子以及由外部场驱动的两态系统，在这些情况中获得了不同时间尺度下的功mgf，并与蒙特卡罗模拟进行了比较。
