论文摘要
我们提出了一种基于电磁诱导的透明度（EIT）的增益辅助量子热发动机（QHE）的方案。 QHE由一个三级{λ}型原子系统组成，该系统与两个热储层和一个耦合场相互作用。没有反转的增益是通过自发产生的相干性（SGC）在两个较低级别之间引起的。 SGC对系统的动力学有重大影响，从而增强了QHE的发射横截面和光谱亮度。
We present a scheme to realize a gain-assisted quantum heat engine (QHE) based on electromagnetically induced transparency (EIT). The QHE consists of a three-level { Λ}-type atomic system that interacts with two thermal reservoirs and a coupling field. The gain without inversion is induced in the system via spontaneously generated coherence (SGC) between two lower levels. The SGC has a significant effect on the system's dynamics, resulting in an enhancement of the emission cross-section and spectral brightness of the QHE.
