论文摘要
我们研究了在有限的时间间隔内开放量子系统进化的发电机的粗粒方法。该方法不需要世俗的近似，但通常会导致Lindblad-Gorini-Kossakowski-Sudarshan发电机。通过将形式主义与完整的计数统计结合在一起，我们可以证明一旦包括了耦合和与储层的耦合和解耦所需的切换工作。特别是，我们可以以标准形式编写第二定律，唯一的区别是必须针对储层定义热电流。我们以简单但教学的例子来体现我们的发现。
We study the coarse-graining approach to derive a generator for the evolution of an open quantum system over a finite time interval. The approach does not require a secular approximation but nevertheless generally leads to a Lindblad-Gorini-Kossakowski-Sudarshan generator. By combining the formalism with Full Counting Statistics, we can demonstrate a consistent thermodynamic framework, once the switching work required for the coupling and decoupling with the reservoir is included. Particularly, we can write the second law in standard form, with the only difference that heat currents must be defined with respect to the reservoir. We exemplify our findings with simple but pedagogical examples.
