利用Fano相干性提高光伏效率
Improvement of photovoltaic efficiency by Fano coherence
摘要：
我们发现，在三能级系统的衰变通道中的Fano共振可以导致相当大的吸收增强和发射抑制。我们发现，建立在基态的二重态的相干性，与强度取决于耦合参数，产生的Fano干涉，原则上可以导致打破原子系统中的吸收和发射过程之间的细节平衡。
英文摘要：
We show that Fano resonance in the decay channels of a three-level system can lead to considerably absorption enhancement and emission suppression. We found that a coherence built up in the ground doublet states, with strength depending on a coupling parameter that arises from the Fano interference, can in principle lead to breaking of the detail balance between the absorption and emission processes in atomic systems.
