论文摘要
量子热力学新兴领域中的基本问题之一是连贯性在量子水平上发生的能量过程中所起的作用。在这里，我们通过研究了两个不同的量子版本的热力学定律，这些定律源自工作和热量的经典定义。通过这样做，我们发现两种情况之间存在数学上的不一致性。我们进一步表明，连贯性动力学的能量贡献是建立一致性的关键要素。为了说明我们的发现，讨论了一些涉及两级原子系统的示例。
One of the fundamental questions in the emerging field of quantum thermodynamics is the role played by coherence in energetic processes that occur at the quantum level. Here, we address this issue by investigating two different quantum versions of the first law of thermodynamics, derived from the classical definitions of work and heat. By doing so, we find out that there exists a mathematical inconsistency between both scenarios. We further show that the energetic contribution of the dynamics of coherence is the key ingredient to establish the consistency. Some examples involving two-level atomic systems are discussed in order to illustrate our findings.
