论文摘要
我们提出了一个马尔可夫量子主方程，该方程可以通过假设标准腔量子电动力学系统直接描述FANO效应。该框架使我们能够概括Fano公式，该公式适用于具有纯dephasing的弱且强的耦合方案。还以一致的方式给出了其发射光谱的表述。然后，我们发现负责FANO效应的干扰是可靠的，可抵抗纯dephasing。这是违反直觉的，因为一般而言，干扰的影响会严重降低了反谐波过程。因此，我们的方法为FANO效应的理论处理提供了基础，以及对开放量子系统中量子干扰的新见解。
We propose a Markovian quantum master equation that can describe the Fano effect directly, by assuming a standard cavity quantum electrodynamics system. The framework allows us to generalize the Fano formula, applicable over the weak and strong coupling regimes with pure dephasing. A formulation of its emission spectrum is also given in a consistent manner. We then find that the interference responsible for the Fano effect is robust against pure dephasing. This is counterintuitive because the impact of interference is, in general, severely reduced by decoherence processes. Our approach thus provides a basis for theoretical treatments of the Fano effect and new insights into the quantum interference in open quantum systems.
