论文摘要
FANO效应是由于两个耗散通道对辐射连续体之间的干扰产生的，因此可以调整光子统计数据。了解FANO效应和实现强光子相关性的作用既具有基本意义，又具有显着性。我们提出了基于空腔量子电动力学的Fano增强光子相关性的分析描述，以表明Atom-Cavity Systems中的Fano效应可以提高四个数量级以上的抗抗激素程度。增强因素和最佳条件是明确给出的，并发现与Fano参数$ Q $有关。值得注意的是，FANO增强表现出针对破坏过程的鲁棒性，并且可以在弱耦合方面生存。我们希望我们的工作可以通过FANO效应来调整光子统计数据，这提供了增强光子相关性的新途径，以及在不需要强烈的光线相互作用的情况下在更广泛的系统中产生非经典光的可能性。
Fano effect arising from interference between two dissipation channels to the radiation continuum enables to tune the photon statistics. Understanding the role of Fano effect and exploiting to achieve strong photon correlations are of both fundamental and applied significance. We present an analytical description of Fano-enhanced photon correlations based on cavity quantum electrodynamics to show that, the Fano effect in atom-cavity systems can improve the degree of antibunching by over four orders of magnitude. The enhancement factors and the optimal conditions are explicitly given, and found related to the Fano parameter $q$. Remarkably, the Fano enhancement manifests robustness against the decoherence processes, and can survive in the weak coupling regime. We expect our work to provide insight in tuning the photon statistics through Fano effect, which offers a new route to enhance the photon correlations, as well as the possibility of generating nonclassical light in a wider diversity of systems without the need of strong light-matter interaction.
