摘要翻译:
本文通过一个紧凑而一般的推导,分析了控制被操纵的随机系统与环境交换的功和热的分布演化的方程。对于在调和势中被拖拽的布朗粒子,我们得到了这些方程的显式解。我们成功地将预测结果与实验结果进行了比较,实验包括用激光阱拖动微米大小的胶体颗粒穿过水。

英文摘要:
We analyze the equations governing the evolution of distributions of the work and the heat exchanged with the environment by a manipulated stochastic system, by means of a compact and general derivation. We obtain explicit solutions for these equations for the case of a dragged Brownian particle in a harmonic potential. We successfully compare the resulting predictions with the outcomes of experiments, consisting in dragging a micron-sized colloidal particle through water with a laser trap.
