摘要翻译:
用路径积分方法讨论了拖拽大质量布朗粒子模型中维持系统处于非平衡稳态的功的涨落中的惯性效应。我们在实验室和同室中计算了功的分布函数,并在任意初始条件下证明了这些功的渐近涨落定理。两个框架中的功涨落在有限时间内出现了重要的可观察的差异,并对非平衡稳态初始条件进行了具体讨论。我们还证明了当质量大于非零临界值时,在有限时间内,功分布函数出现时间振荡行为。

英文摘要:
Inertial effects in fluctuations of the work to sustain a system in a nonequilibrium steady state are discussed for a dragged massive Brownian particle model using a path integral approach. We calculate the work distribution function in the laboratory and comoving frames and prove the asymptotic fluctuation theorem for these works for any initial condition. Important and observable differences between the work fluctuations in the two frames appear for finite times and are discussed concretely for a nonequilibrium steady state initial condition. We also show that for finite times a time oscillatory behavior appears in the work distribution function for masses larger than a nonzero critical value.
