论文摘要
我们从理论上散文和调查了一个光孔引擎，该引擎正在与光腔内部的单模辐射场一起工作，并由热储层和冷藏库驱动，在那里，通过发送一对相关的两级原子之一，通过将一个相关的两级原子传递到光学腔中，可以通过寒冷的腔，而冷藏池则是由寒冷的腔和非插入的collections组成的。就原子对的量子不一致而言，我们得出了性能参数（功率和效率）和稳定性度量（功率变化系数）的分析表达式。我们表明，量子不和谐提高了量子引擎的性能和效率，甚至可能会改变操作模式。我们还证明，量子不和谐通过降低满足广义热力学不确定性关系的功率变化系数来提高机器的稳定性。最后，我们发现这些结果可以转移到另一个照片 - 奥托发动机模型中，在该模型中，光腔也可以偶联与热的热玻色子浴以及两对束相关的原子，这些原子起着冷库的作用。
We theoretically prose and investigate a photo-Otto engine that is working with a single-mode radiation field inside an optical cavity and alternatively driven by a hot and a cold reservoir, where the hot reservoir is realized by sending one of a pair of correlated two-level atoms to pass through the optical cavity, and the cold one is made of a collection of noninteracting boson modes. In terms of the quantum discord of the pair of atoms, we derive the analytical expressions for the performance parameters (power and efficiency) and stability measure (coefficient of variation for power). We show that quantum discord boosts the performance and efficiency of the quantum engine, and even may change the operation mode. We also demonstrate that quantum discord improves the stability of machine by decreasing the coefficient of variation for power which satisfies the generalized thermodynamic uncertainty relation. Finally, we find that these results can be transferred to another photo-Otto engine model, where the optical cavity is alternatively coupled to a hot thermal bosonic bath and to a beam of pairs of the two correlated atoms that play the role of a cold reservoir.
